[Settimanale] avviso seminario di matematica prof. Laurent Vuillon (5.11.2020)

SEMINARIO DI MATEMATICA *Giovedì 5 novembre 2020* ore 14:30 *Scuola Normale Superiore* Pisa *Laurent Vuillon* *(Università di Savoie Mont Blanc**)* Terrà un seminario dal titolo: *“Data science for protein structures and molecular dynamics”* *Abstract:* In this talk, we investigate the structure of proteins by considering the network associated with the adjacent amino acids according to a given cutoff. This network allows us to understand the protein structures and to study interfaces in polymers. We also use a dynamical version of these networks to study the allosteric paths in proteins. Indeed, elucidation of the allosteric pathways in proteins is a computational challenge that strongly benefits from combination of atomistic molecular dynamics (MD) simulations and coarse-grained analysis of the complex dynamical network of chemical interactions based on graph theory. Here, we introduce and assess the performances of the dynamical perturbation network analysis of allosteric pathways in a prototypical V-type allosteric enzyme. Dynamical atomic contacts obtained from MD simulations are used to weight the allosteric protein graph, which involves an extended network of contacts perturbed by the effector binding in the allosteric site. The outcome showed good agreement with previously reported theoretical and experimental extended studies and it provided recognition of new potential allosteric spots that can be exploited in future mutagenesis experiments. Overall, the dynamical perturbation network analysis proved to be a powerful computational tool, complementary to other network-based approaches that can assist the full exploitation of allosteric phenomena for advances in protein engineering and rational drug design. *Il seminario si svolgerà in modalità telematica su Google Meet* Meet: 5 novembre 14:30, https://meet.google.com/jby-iuhu-bmy Valeria Giuliani Scuola Normale Superiore Servizio alla Didattica e Allievi tel. 050 509260 Piazza dei Cavalieri, 7 56126 Pisa E-mail: valeria.giuliani(a)sns.it E-mail: classi(a)sns.it -- Hai ricevuto questo messaggio perché sei iscritto al gruppo "Matematici.Esterni.SNS" di Google Gruppi.

SEMINARIO DI MATEMATICA *Mercoledì 28 ottobre 2020* ore 17:00 *Scuola Normale Superiore* Pisa Aula Mancini *Mattia Fogagnolo* *(**Scuola Normale Superiore)* Terrà un seminario dal titolo: *“Strictly outward minimizing hulls, p-capacities and isoperimetric inequalities”* *Abstract:* We investigate the notion of strictly outward minimizing hull and prove that under natural geometric assumptions on the ambient manifold the it gives a maximal volume solution to the least area problem with obstacle. Moreover, we recover the value of its area as limit of p-capacities. Finally, we apply some of these results in order to obtain the sharp isoperimetric inequality on manifolds with nonnegative Ricci curvature and Euclidean volume growth up to dimension 7, up to now known only in dimension 3. *!!

[Settimanale] annuncio seminario di matematica prof. Philipp Forstner (22.07.2020)

20 Jul '20

*Announcement* On Wednesday 22, July, h. 14:00 (Pisa time) Philipp Forstner, TU Darmstadt will give a talk, invited by Scuola Normale Superiore: Title: SQG driven by Space-Time White Noise: An Approach using Regularity Structures Abstract: We show the existence of solutions of the 2D dissipative surface quasi-geostrophic equation driven by space-time white noise. Solutions will be obtained as a limit of solutions to regularised and renormalised equations. Therefore, we give a short introduction into the theory of regularity structures and show how the renormalisation procedure is done.

[Settimanale] Avviso seminari di matematica, proff. David Rydh e Roberto Pirisi (4.03.2020)
by Valeria Giuliani 03 Mar '20

03 Mar '20

*AVVISO SEMINARI DI MATEMATICA* ------------------------------ Data: mercoledì 4 MARZO 2020 Luogo: Aula Magna del Dipartimento di Matematica di Pisa Programma: 15:00--16:00 David Rydh (Stockholm): Derived blow-ups and deformation to the normal cone Abstract: I will describe the functor of points of blow-ups and deformations to the normal cone using derived algebraic geometry. One application is a natural and easy construction of virtual fundamental classes and virtual pull-backs. Another potential application is to Kirwan partial desingularization and the generalized DT-invariants recently constructed by Kiem, Li and Savvas. This is joint work with A. Khan. 16:00--16:30 Coffee break 16:30--17:30 Roberto Pirisi (Stockholm): Brauer groups of moduli of hyperelliptic curves, via cohomological invariants Abstract: We use the theory of cohomological invariants for algebraic stacks to completely describe the Brauer group of the moduli stacks H_g of genus g hyperellitic curves over fields of characteristic zero, and the prime-to-char(k) part in positive characteristic. It turns out that the (non-trivial part of the) group is generated by cyclic algebras, by an element coming from a map to the classifying stack of étale algebras of degree 2g+2, and when g is odd by the Brauer-Severi fibration induced by taking the quotient of the universal curve by the hyperelliptic involution. This paints a richer picture than in the case of elliptic curves, where all non-trivial elements come from cyclic algebras. This is joint work with Andrea di Lorenzo. -- Hai ricevuto questo messaggio perché sei iscritto al gruppo "Matematici.Esterni.SNS" di Google Gruppi.
