Basics of the BV formalism - Part 2

If the Batalin-Vilkovisky formalism is a cohomological handle for field theories in the Lagrangian formalism, a similar construction can be set up for the associated Hamiltonian picture and goes under the name of Batalin, Fradkin and Vilkovisky (BFV).
The link between the two has been made explicit recently by Cattaneo, Mnev and Reshetikhin (CMR) as a tool to treat field theories on manifolds with boundary.
In this talk I will review the basics of the BFV and CMR constructions and show how they relate to what we have done so far.

Gromov-Hausdorff limits of curves with flat metrics and non-Archimedean geometry

The subject of this talk is the study of the Gromov-Hausdorff limit of
a family of complex curves over a punctured disc with maximal
unipotent monodromy endowed with normalized flat metrics with conical
singularities. The limit turns out to be a metric graph which can be
naturally identified with a quotient of a subset of the Berkovich
analytic space associated to the family. This problem is inspired by
the approach of Kontsevich and Soibelman to the SYZ conjecture, and,
time permitting, I will discuss how the techniques of the talk can be

The essential coexistence phenomenon in Hamiltonian dynamics

MPIM Seminar Room

I will discuss a phenomenon of the essential coexistence of regular (zero Lyapunov exponents and hence, zero entropy) dynamics and chaotic (non-zero Lyapunov exponents and positive entropy) dynamics in the setting of smooth dynamical systems. I will review some recent results in this direction, discuss some open problems and describe some new examples of essential coexistence. In particular, I will outline a construction of a Hamiltonian system which demonstrate a "complete? KAM-type picture of coexistence of invariant KAM tori and surrounding "chaotic sea".

Number theory lunch seminar

Given two semistable elliptic surfaces over a smooth, projective curve $C$ defined over a field of characteristic zero or finitely generated over its prime field,  we show that any compatible family of effective isometries of the N{\'e}ron-Severi lattices of the base changed elliptic surfaces for all finite separable maps $B\to C$ arises from
an isomorphism of the elliptic surfaces. Without the effectivity hypothesis, we show that the two elliptic surfaces are isomorphic.

We consider an analogue of the classical Polya-Vinogradov inequality for character sums in
the context of the group GL(2) over finite fields. This is joint work with Satadal Ganguly.

Friedrich Hirzebruch Lecture

Posted in
Location:
University Club Bonn

The annual Friedrich Hirzebruch Lecture is a series of lectures started in 2007 on the occasion of the 80th birthday of Prof. Friedrich Hirzebruch. The lectures address a general audience and aim at illustrating the relation between mathematics and art, society and other fields.
