Subject: DDT&G seminar this week in Leiden: Ioan Marcut on Linearization of Poisson Structures


Dear colleagues,



You are cordially invited to attend the next Dutch Differential Topology and Geometry seminar, which will take place later this week in Leiden.



Speaker: Ioan Marcut (RU)

Title: "The linearization problem in Poisson geometry" (see below for the abstract)

Date: Friday 15 December, 14:00-16:30

Location: Leiden, Snellius 412



The schedule will be as follows:



2:00-3:00 p.m.: first part of the seminar (little to no prior knowledge assumed)

3:30-4:30 p.m.: second part of the seminar (slightly more advanced level)



Please notice that the first part of the seminar (2:00-3:00 p.m.) is intended for general mathematical audience, and master students with an interest in geometry and topology are especially encouraged to participate.



Please visit the seminar's webpage for additional information and an overview of past and upcoming talks:

We would also like to remind you that most of the previous lectures are available on the YouTube channel of the seminar:

We hope to see many of you on Friday!

Abstract
Ever since Alan Weinstein’s foundational 1983 paper, the local
structure of Poisson manifolds has been a central problem in Poisson
Geometry. Among other results, the paper contains the Splitting Theorem for Poisson structures, the formulation of the linearization problem and several conjectures, some of which have been solved soon thereafter by Jack Conn.
In this talk, first I will explain these classical linearization theorems and some open problems. Then I will focus on recent work with my former PhD student, Florian Zeiser, about singularities with isotropy sl_2(C).
