[Coloquio del DM]

Estimada comunidad,

El 18 de octubre a las 14 hs tendremos otro coloquio del DM-IMAS (FCEN-UBA).

Hablará Javier Fernández de Bobadilla (BCAM). Más abajo les compartimos el
título y el resumen de la charla, y una breve bio del orador.

Título: Zariski multiplicity conjecture: Hamiltonian mechanics hits
Algebraic Geometry

Resumen: I will explain the main ingredients of my joint proof together
with Tomasz Pelka of Zariski's multiplicity conjecture for families of
isolated hypersurface singularities. While Zariski's multiplicity
conjecture in families admits a purely algebraic formulation, its solution
involves techniques from symplectic dynamics and pseudohomolomorphic
curves. In fact it is tightly related to the proof of Arnol'd conjecture
bounding below the number of fixed points of Hamiltonian symplectmorphims
of a compact symplectic manifold by the sum of its Betti numbers.

Bio: He got a Ph. D at Nijmegen university and now is an Ikerbasque
research professor at BCAM. Previously he held positions at UNED (Madrid),
University of Utrecht (The Netherlands), ICMAT (Madrid). He held visiting
positions at Renyi Institute (Budapest), IMPA (Rio de Janeiro), IAS
(Princeton), and held Chaire Jean Morlet at CIRM  in the second semester
of 2021. He held 2 European Research Council Grants (Starting grant and
Consolidator grant). He was a Member of the jury of the prize for Science
and Engineering of Banco de Sabadell 2017-2022 and is a member of the
Meetings Committee of the European Mathematical Society (2018-2024). He is
managing editor of Journal of Singularities and editor of Journal and
Bulletin of the London Mathematical Society. He works in Singularity
Theory and Algebraic Geometry and is known by the Solutions of Zariski's
question B, the Nash conjecture for surfaces (with M. Pe Pereira), and
Zariski's conjecture for families of isolated singularities (with T.
Pelka).

El coloquio será en la Sala de Conferencias DM/IMAS.

Saludos cordiales,
