_ICTP MATHEMATICS COLLOQUIUM_

*"Complex quasi-projective varieties and their fundamental groups" by 
Professor Helene Esnault*

_Abstract:
_A building block of homotopy theory is the fundamental group of 
varieties, in topology and in arithmetic geometry. We know very little 
on it. One way to approach it is via local systems, that is linear 
representations modulo conjugation. In doing so we lose a lot of 
information. Still arithmetic geometry  (notably the Langlands program) 
yields obstructions for a finitely presented group to be the fundamental 
group of a smooth complex quasi-projective variety.

The Mathematics Colloquium will take place on _Tuesday, 10 December 2024 
at 14:00_ (Central European Time)

In Presence: Leonardo Building -_Luigi Stasi Seminar Room_

Helene Esnault* is a mathematician specializing in algebraic and 
arithmetic geometry. She obtained her PhD in 1976 at the University of 
Paris VII under the direction of Lr Dung Trang. She was a Heisenberg 
scholar at the MPI in Bonn and maître de conférence in Paris VII. In 
1990, she became a full professor at the Universität Duisburg-Essen. In 
2012, she moved to Berlin as the first Einstein Professor at the Freie 
Universität Berlin, where she became emerita in 2019. She continued her 
mathematical work and accepted a visiting professor position in 2019 at 
IAS Princeton. In the fall 2022, she held the Eilenberg Chair at 
Columbia University and is currently a part-time professor at Copenhagen 
University and a Faculty Associate at Harvard University.

As a mathematician, she published more than 135 research articles with 
45 coauthors covering a wide range of topics. In recognition of her 
seminal contributions, she was awarded the Doisteau-Blutet prize of the 
Academy of Sciences in Paris in 2001, jointly with Eckart Viehweg  the 
Leibniz Prize in 2003 and received the Cantor medal of the German 
Mathematical Society in 2019. She received multiple honorary doctorates 
and was a member of various significant committees, including the Fields 
Medal Committee, the Structure Committee, the Shaw Prize Committee, and 
the Infosys Prize Committee. Additionally, she has served on the 
editorial boards of several prestigious journals.
