[Indico] Justin Sawon, Mirror symmetry for generalized Kummer varieties, 29/06/2022, 15:30 Europe/Rome
by francesco.sala＠unipi.it 28 Jun '22

Title: Mirror symmetry for generalized Kummer varieties, Speaker(s): Justin Sawon, University of North Carolina at Chapel Hill, USA, Date and time: 29 Jun 2022, 15:30 (Europe/Rome), Lecture series: Algebraic and Arithmetic Geometry Seminar, Venue: Department of Mathematics (Aula Riunioni). You can access the full event here: https://events.dm.unipi.it/e/99 Abstract -------- The generalized Kummer variety $K_n$ of an abelian surface $A$ is the fibre of the natural map $\mathsf{Hilb}^{n+1}A\to \mathsf{Sym}^{n+1}A\to A$. Debarre described a Lagrangian fibration on $K_n$ whose fibres are the kernels of $\mathsf{Jac}C\to A$, where $C$ are curves in a fixed linear system in $A$. In this talk we consider the dual of the Debarre system, constructed in a similar way to the duality between $\mathsf{SL}$- and $\mathsf{PGL}$-Hitchin systems described by Hausel and Thaddeus. We conjecture that these dual fibrations are mirror symmetric, in the sense that their (stringy) Hodge numbers are equal, and we verify this in a few cases. In fact, there is another isotrivial Lagrangian fibration on $K_n$. We can describe its dual fibration and verify the mirror symmetry relation in many more cases. -- Indico :: Email Notifier https://events.dm.unipi.it/e/99

[Indico] Nicola Tarasca, Geometry of vertex operator algebras on moduli of curves, 29/06/2022, 14:30 Europe/Rome

Title: Geometry of vertex operator algebras on moduli of curves, Speaker(s): Nicola Tarasca, Virginia Commonwealth University, Date and time: 29 Jun 2022, 14:30 (Europe/Rome), Lecture series: Algebraic and Arithmetic Geometry Seminar, Venue: Department of Mathematics (Aula Riunioni). You can access the full event here: https://events.dm.unipi.it/e/87 Abstract -------- The physically-inspired theory of conformal blocks allows one to construct vector bundles on moduli spaces of curves with remarkable geometric and combinatorial properties. This theory uses as input the representations of some non-commutative algebras. A classical example is provided by the representations of affine Lie algebras, and the resulting vector bundles have been studied at great length in the last thirty years, yielding extraordinary insights on moduli spaces of curves. In this talk, I will present how some fundamental results of the classical theory of conformal blocks extend to the more general setting provided by replacing affine Lie algebras with vertex operator algebras. Specifically, I will discuss an extended factorization property and new cohomological field theories. This is joint work with Chiara Damiolini and Angela Gibney. -- Indico :: Email Notifier https://events.dm.unipi.it/e/87

Seminario di Matematica - Marco Volpe (Università di Regensburg)
by Guglielmo Nocera 02 Jun '22

02 Jun '22

*Avviso seminario* Lunedì 6 giugno 2022 alle ore *14:00* in aula Tonelli (SNS) *Marco Volpe*, dell'Università di Regensburg, terrà un seminario dal titolo *Formalismo dei sei funtori e dualità di Atiyah per varietà topologiche* Abstract: In topologia il formalismo dei sei funtori, originariamente introdotto da Grothendieck nel contesto algebro-geometrico, consiste di un insieme di operazioni tra categorie derivate di fasci in gruppi abeliani, attraverso le quali è possibile dedurre le proprietà principali della coomologia singolare, tra cui la dualità di Poincaré. In questo talk spiegheremo come estendere il formalismo a fasci a valori in spettri, utilizzando il linguaggio delle ∞-categorie. Come applicazione otterremo una generalizzazione della dualità di Atiyah per sommersioni topologiche proprie, usando una costruzione fascio-teoretica dello spettro di Thom di un microfibrato. Prerequisiti: Categorie triangolate, funtori aggiunti, un primo corso in topologia algebrica, coomologia, spettri, fasci su spazi topologici. L'impostazione del seminario sarà tale da non assumere confidenza con il linguaggio delle ∞-categorie.

Seminario
by Andrea Tamburelli 31 May '22

31 May '22

Buongiorno, Vi segnalo un seminario questo pomeriggio in aula riunioni. Saluti, Andrea ______________________________________________________________________________________________ 31 Maggio 2022, 16:30 - 17:30, Aula Riunioni Nicholas Rungi (SISSA) Titolo: Pseudo-Kähler geometry of properly convex projective structures in a linear case Abstract: In this talk we will define a pseudo-Kähler structure on the deformation space of properly convex projective structures over the 2-dimensional torus. The symplectic form and the pseudo-Riemannian metric are both compatible with the complex structure inherited from the identification of this space with the total space of the holomorphic vector bundle of cubic differentials over Teichmuller space. I will also explain briefly what we expect in higher genus and the strategy to solve the problem. This is the first part of an ongoing PhD research project under the supervision of Dr. A. Tamburelli.
