martedi' 11-07-2006 (15:00) - Sala Seminari Gordana Matic' (University of Georgia, Athens) : On right-veering diffeomorphisms and contact class in Heegaard Floer homology Abstract: We present an alternate deion of the Ozsv'ath-Szab'o contact class in Heegaard Floer homology. Using our deion of the contact class, we prove that if a contact structure $(M,\xi)$ has an adapted open book decomposition whose page $S$ is a once-punctured torus, then the monodromy is right-veering if and only if the contact structure is tight. _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale

AVVISO IMPORTANTE Si segnala che, per motivi organizzativi non previsti, il COLLOQUIO DE GIORGI annunciato per martedi' 11 luglio (del quale si acclude l'avviso) SI TERRA' ECCEZIONALMENTE IN AULA BIANCHI. COLLOQUIO DE GIORGI Simon Gindikin Rutgers University "Harmonic analysis on complex semisimple groups and symmetric spaces from point of view of complex analysis" Abstract In the classical conception of harmonic analysis on semisimple groups of E. Cartan and H. Weyl there was very essential interaction between algebraic and transcendental (analytic) methods. It looks that one more possibility - to start from the complex analysis on groups - was never systematically considered. Since all complex semisimple groups are Stein manifolds and all spherical functions are holomorphic, this way deserves an attention. If to choose this way then we will start not from characters or irreducible representations but from Cauchy integral formula on these groups. It turns out that there is a beautiful explicit Cauchy formula on all semisimple Lie groups and, more general, on all symmetric Stein manifolds and this formula will be the basic subject of this talk. This formula, similarly to the situation in one-dimensional complex analysis, is a base of complex analysis on these symmetric spaces, which incorporates the classical harmonic analysis and adds some new facts.

27/06 Aula seminari ore 15 J.M. Schlenker (Universite' Paul Sabatier, Toulouse) Titolo: "3-dimensional manifolds with particles". Abstract: A "particle" in a 3-dimensional hyperbolic 3-manifold is a cone singularity along an infinite line, with an angle which is less than $\pi$. There is a natural notion of quasi-Fuchsian manifold with particles, and those appear to share many of the striking geometric properties of (non-singular) quasi-Fuchsian 3-manifolds. We will describe some examples of properties which can be extended to this context. Quasi-Fuchsian 3-manifolds with particles also have a Lorentzian counterpart, GHMC AdS manifolds with particles, to which some properties of Mess' GHMC AdS manifolds can be extended. 29/06 Aula riunioni ore 15 G. Mondello (MIT) Titolo: Cicli di Witten sullo spazio dei moduli delle superfici di Riemann Abstract: Ogni presentation dello spazio dei moduli delle superfici di Riemann da` origini a classi caratteristiche "naturali". Dal punto di vista algebro-geometrico, esse sono le cosiddette classi tautologiche. D'altra parte, la decomposizione cellulare dello spazio dei moduli per mezzo di grafi a nastro consente di definire cicli combinatorici interessanti, che sono anche chiamati cicli di Witten. Lo scopo del seminario e` di illustrare alcune idee della dimostrazione della congettura di Witten-Kontsevich (i cicli combinatorici sono tautologici) e, se il tempo lo consente, accennare a possibili applicazioni e generalizzazioni. ************************* Segreteria Didattica Giulia Curciarello tel- 050 2213219 ************************* _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale

SEMINARIO DI MATEMATICA Giovedì 6 luglio 2006 ore 16.00 Scuola Normale Superiore Pisa (Aula Tonelli) David W. MASSER Università di Basilea Terrà un seminario dal titolo: "Linear equations in multiplicative groups over positive characteristic" Abstract The equation $a_1x_1+...+a_nx_n=1$, to be solved in unknowns $x_1,...,x_n$ lying in a fixed multiplicative group, has been much studied in the case of zero characteristic. However there are not many results over positive characteristic. This case is generally easier to handle, but it presents interesting new features. For example, although the equation can have infinite $(n-2)$-parameter families of solutions, these can be classified and estimated in a completely effective way. This has applications to multiple mixing problems for algebraic actions on disconnected compact abelian groups. Tutti gli interessati sono invitati a partecipare.

For real analytic curves this reduces to the local problem for germs at singular points. For those germs, the problem splits into the consideration of their irreducible branches. Now, irreducible curve germs are classically discussed using the semigroup of values: all irreducible curves with fixed semigroup form a "moduli" algebraic set in some finite dimensional affine space. There, Pythagoras numbers, positive semidefinite germs, sum of squares provide semialgebraic mappings on and stratifications of the "moduli" set. The understanding od these semialgebraic data is a difficult matter that has surprising connections with classical concepts (for instance, Arf curves and Pythagorean curves are one and the same thing). ************************* Segreteria Didattica Giulia Curciarello tel- 050 2213219 ************************* _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale _______________________________________________ Utenti mailing list Utenti(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/utenti _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale

Such flows arise as minimal components of flows on surfaces given by multi-valued Hamiltonians. We prove that if the roof function has an asymmetric logarithmic singularity, the suspension flow is strongly mixing for a full measure set of interval exchanges. This generalizes a result by Khanin and Sinai for flows over rotations of the circle. In the proof we use a recent result by Avila-Gouzel-Yoccoz. ************************* Segreteria Didattica Giulia Curciarello tel- 050 2213219 ************************* _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale

I seminari inizieranno alle 15 e proseguiranno con il seguente programma martedi' 13-06-2006 (15:00) - l'Aula Magna del Dipartimento di Matematica "L. Tonelli" Giandomenico Orlandi : One day miniworkshop on Variational Problems:Dynamics of Ginzburg-Landau vortices and critical points of the Kirchhoff functional. Abstract: For the two dimensional complex parabolic Ginzburg-Landau equation we prove that, asymptotically, vortices evolve according to a simple ordinary differential equation, which is a gradient flow of the Kirchhoff-Onsager functional. This convergence holds except for a finite number of times, corresponding to vortex collisions and splittings, which we describe carefully. The only assumption is a natural energy bound on the initial data. martedi' 13-06-2006 (16:00) - l'Aula Magna del Dipartimento Cyrill Muratov : "One day miniworkshop on Variational Problems". A Variational Approach to Front Propagation in Infinite Cylinders. Abstract: Gradient reaction-diffusion-advection systems arise in the context of modeling the kinetics of phase transitions, population dynamics and combustion. These systems are known to exhibit a variety of non-trivial spatio-temporal behaviors, most notably the phenomenon of propagation and traveling waves. We introduce a variational formulation for the traveling wave solutions in cylindrical geometries with transverse potential flow, which allows us to construct a certain class of traveling wave solutions and establish their monotonicity, asymptotic decay and, under some extra assumptions, uniqueness. These solutions are special in a sense that they are characterized by a non-generic fast exponential decay ahead of the wave and play an important role in propagation phenomena for the initial value problem. We also construct an area-type functional that gives a matching upper and lower bound for the propagation speed in the sharp reaction zone limit for weakly curved fronts. ore 17.00 coffe-break martedi' 13-06-2006 (17:30) - l'Aula Magna del Dipartimento "L. Tonelli" Dorin Bucur : "One day miniworkshop on Variational Problems". Shape analysis of the crack inverse problem Abstract: The talk deals with the identifiability of non-smooth defects by boundary measurements, and the stability of their detection. We extend the result of Alessandrini and Valenzuela on the unique determination of a finite number of cracks or cavities by two boundary measurements, to arbitrary closed sets satisfying quasi-everywhere a {\it conductivity assumption}. This new regularity concept is to be compared to the Wiener criterion, rather than to the usual smoothness of the boundary. Relying on the geometric stability of the direct problem, we discuss the stability of the inverse problem without imposing any a priori boundary regularity of the unknown defects. As an application, we give a rigorous justification of the finite elements approximation of the defects. ***************************************************************** lunedi' 19-06-2006 (11:00) - Sala riunioni Irinel Dragan (Dept. of Mathematics, Univ.of Texas at Arlington, USA) : seminari congiunti col DIPART.MATEMATICA APPLICATA: On the Semivalues and the Shapley value for cooperative transferable utility games ******************************************************************* mercoledi' 21-06-2006 (15:00) - Sala dei Seminari Jesus Ruiz (Universitad Complutense Madrid) : Open questions concernings Hilbert's 17th Problem for analytic curves Abstract The Hilbert 17th Problem asks when a psd function is a sum of squares, and of how many.

AVVISO DI SEMINARIO --------------------------------------------------------------- Nei giorni 14 e 15 giugno il Prof. Igor Konnov (Kazan University) terrà 2 seminari nella Sala Seminari del Dipartimento di Matematica Applicata "U. Dini" - Università di Pisa, via Bonanno 25/b, Pisa. 14 giugno ore 10: Combined Relaxation Methods for Variational Inequalities with Single-valued Mappings ABSTRACT: Variational inequalities proved to be a very useful and powerful tool for investigation and solution of many equilibrium type problems in Economics, Engineering,Operations Research and Mathematical Physics. The talk is devoted to a new general approach to constructing solution methods for variational inequalities, which was called the combined relaxation (CR) approach. This approach is based on combining, modifying and generalizing ideas contained in various relaxation methods. We describe the methods for variational inequality problems with single-valued mappings. 15 giugno ore 10: Combined Relaxation Methods for Variational Inequalities with Multi-valued Mappings ABSTRACT: We intend to to describe combined relaxation (CR) methods for variational inequality problems with multi-valued mappings. The basic principles of the CR approach claim that an iteration of most descent methods can serve as a basis for the auxiliary procedure with a regular rule of determining a separating hyperplane and that there are a number of rules for choosing the parameters of both the levels. Following these principles, we now indicate ways of creating various classes of CR methods. We begin our considerations from the mixed variational inequalities which constitute a significant subclass of these problems. ------------------------------------------------------------------ Mauro Passacantando Department of Applied Mathematics Antonella Giacomelli Dipartimento di Matematica Applicata "U.Dini" Via Bonanno Pisano 25 B 56126 - Pisa Tel.: 050 2219452 Fax: 050 2219450 _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale

I will therefore devote some lectures to the numerical > analysis of the stochastic NLS equations and explain how the associated > infinite dimensional Kolmogorov equation is used to study the weak order > of a scheme. > Finally, depending on the time spent on the preceding topics, I will > adress some problems related to the Korteweg-de Vries equation and the > associated solitons when a noise perturbs the dynamics. > > CALENDARIO: > Lunedi' 12 Giugno, 14-30-16-30 > Lunedi' 19 Giugno, 14-30-16-30 > Venerdi' 23 Giugno, 14-30-16-30 > Lunedi' 26 Giugno, 14-30-16-30 > Venerdi' 30 Giugno, 14-30-16-30 > Lunedi' 3 Luglio, 10.30-12.30 > Venerdi' 7 Luglio, 10.30-12.30 > Lunedi' 10 Luglio, 10.30-12.30 > Lunedi' 17 Luglio, 10.30-12.30 > Venerdi' 21 Luglio,, 10.30-12.30 > > Le lezioni si terranno nella Sala Conferenze del Collegio Puteano > (Piazza dei Cavalieri 3, PISA). > > Tutti gli interessati sono invitati a partecipare. _______________________________________________ Settimanale mailing list Settimanale(a)mail.dm.unipi.it https://mail.dm.unipi.it/mailman/listinfo/settimanale
