Seminario domani MATTINA

Buondì, Segnalo (con un po' di ritardo...) un seminario di geometria per domani mattina (con orario inusuale). A presto, Bruno 08-Nov-2018 - 10:00 Sala Seminari (Dip. Matematica) <http://www.dm.unipi.it/webnew/it/aula/sala-seminari-dip-matematica> Short curves in hyperbolic 3-manifolds via knots on Heegaard surfaces <http://www.dm.unipi.it/webnew/it/seminari/short-curves-hyperbolic-3-manifol…> Alessandro Sisto Given a Heegaard splitting of a manifold M, one can consider simple closed curves on the Heegaard surface as elements of its curve graph. I will discuss the result that if some such curve K is far from both disk sets (as measured in the curve graph), then the complement M-K is hyperbolic. Moreover, there is a condition involving subsurface projection that further ensures that M is obtained by long Dehn filling of M-K, yielding that M is hyperbolic and (the geodesic representative of) K is short. If the gluing map of the Heegaard splitting is chosen using a random walk, then with high probability there exists a curve K satisfying the required conditions. Hence, this proves a (Perelman-free) hyperbolisation result for "generic" 3-manifolds, as well as providing information about the injectivity radius. Joint with Peter Feller.

Inoltro avviso di RTD A a Roma in geometria. Ciao, Bruno ---------- Forwarded message --------- From: Gm Gm <gabriele.mond(a)gmail.com> Date: Thu, Oct 4, 2018 at 2:04 PM Subject: Precall: 1 position as 3-year postdoc in geometry in Rome To: Dear all, my department (Sapienza, Mathematics) is about to open a call for a 3-year postdoc (RTD-A) in geometry. The position has light teaching load (1 course per year). Details will appear in the formal call. Usually, at the expiration of such contract a new call for a tenure-track associate professor (RTD-B) will be opened. This is intended to give the opportunity to the postdoc to become tenure-track, though this new call is completely independent of the former one (and a different person could well be hired). Please inform any potential candidate. Thank you! Gabriele Mondello

Seminario giovedì

Buondì, Vi segnalo il seminario di geometria di giovedì prossimo (ore 16 aula seminari). Siete tutti invitati, A presto, Bruno Martelli Thursday, October 4, 2018 16:00 17:00 SEMINARI DI GEOMETRIA Sala Seminari (Dip. Matematica) Transverse invariants from the deformations of Khovanov sl_3 homology Carlo Collari In this talk I will describe some invariants for transverse links in S^3 (endowed with the symmetric contact structure) arising from the deformations of Khovanov sl_3 homology. I will start with a brief introduction to the theory of transverse links in S^3. Afterward, I will recall some known results concerning transverse invariants in link homologies. In particular, I will focus on the invariants coming from Khovanov-Rozansky homologies, and those coming from the deformations of Khovanov homology. After the introductory part, I will briefly describe the construction and the properties of the universal sl_3 link homology, due to Mackaay and Vaz, and define the transverse invariants. These invariants, which are called the \beta_3-invariants, are cycles in the universal sl_3 complex. Finally, I will state a result concerning the vanishing of the homology classes of these invariants, and compare it with similar results known for other invariants. The idea of the proof will be also given. Time permitting, I will also give a number of Bennequin-type inequalities which can be proved using the \beta_3-invariants.
