SCHEDULE
Poisson 2022 Advanced School
to July 22, 2022
Please, stay in this webpage if you are registering just for the Poisson 2022 Advanced School taking place at the CRM or if you are applying for a grant.
Description
The Summer School on Poisson Geometry aims to introduce the participants to Poisson Geometry and related fields, as well as to present some of the most recent developments and open problems in the field. The targeted audience is final-year undergraduate students, graduate students and young researchers. The only required background is basic differential geometry.
The school will consist of four minicourses during one week. There will be problems sessions to promote the participation of the students of the school, and also several activities to foster social interaction.
This school will be followed by a week-long conference which will take place in Madrid.
There will be a topical Issue on the Journal of Geometry and Physics dedicated to Poisson Geometry in Mathematics and Physics.
Editors: Anton Alekseev, Lisa Jeffrey, Eva Miranda and Volodya Roubtsov
(more information will be posted soon)
About Poisson Geometry
Poisson Geometry lies on the crossroads of Mathematical Physics and Geometry. It originates in the mathematical formulation of Hamiltonian mechanics and as the semiclassical limit of quantum systems. Although Poisson structures can be traced back to some of the classical works of the 19th century (Poisson, Hamilton, Jacobi, Lie), Poisson Geometry started as a field around 1980 with the work of Lichnerowicz, Weinstein, etc. The field developed rapidly, stimulated by the connections with a large number of areas in mathematics and mathematical physics, including differential geometry and Lie theory, quantization, noncommutative geometry, representation theory and quantum groups, geometric mechanics, and integrable systems.
Lecturers
Wonderful Compactifications
Lecturer: Ana Balibanu (Harvard)
Chair: Jiang-Hua Lu (Hong Kong)
Abstract: Every complex semisimple group of adjoint type has a canonical, smooth compactification which encodes the asymptotic behavior of the group “at infinity.” It is constructed using representation-theoretic data, and its geometry is indexed by the combinatorics of the corresponding root system. This course will outline some of the remarkable properties of this algebraic variety, and some of its many applications.
Lecture 1: Outline of the construction. Structure theory of the wonderful compactification, its boundary divisor, and distinguished subvarieties.
Lecture 2: Poisson structures associated to the compactification. Poisson homogeneous spaces and the variety of Lagrangian subalgebras.
Lecture 3: Current developments, additive analogues, and connections to combinatorics and algebraic geometry.
Introduction to Poisson Geometry
Lecturer: Henrique Bursztyn (IMPA)
Chair: Eckhard Meinrenken (Toronto)
Abstract: This mini-course will offer a panoramic view of Poisson geometry, including both classical aspects and modern developments of the theory.
We will start with basic definitions and concepts related to Poisson structures, some foundational results (local theory, symplectic leaves) and key examples. We will then discuss symplectic groupoids and more general connections with Lie groupoids and multiplicative geometric structures. I will also introduce Dirac structures, their main properties and various applications, both within and beyond Poisson geometry.
Singular Foliations
Lecturer: Camille Laurent-Gengoux (Metz)
Chair: Rui Fernandes (Urbana-Champaign)
Abstract: Foliations are partitions of a manifold into sub-manifolds called leaves. They are said to be singular when the dimension all some leaves are not constant. Orbits of Lie group actions, symplectic leaves of a Poisson bivector, symmetries of affine varieties are among examples. I will try to give a detailed proof of several basic but subtle theorems about singular foliations and to give an overview of the geometry of their singular leaves.
Lecture 1: Discussion of the various possible definitions of singular foliation. Examples and counter examples. Existence of leaves and local splitting theorem.
Lecture 2: Various algebraic or geometric structures hidden behind a singular foliation: holonomy Lie algebras, holonomy groupoids. Bi-submersions and first-return.
Lecture 3: Open (and closed) questions from algebraic and differential geometry to theoretical physics.
A problem session will take place after Lecture 2.
Geometric quantization, old and new
Lecturer: Jonathan Weitsman (Northeastern University)
Chair: Chenchang Zhu (Goettingen)
Abstract: We give an overview of Geometric Quantization, with an emphasis on examples and on invariance of polarization, and on applications to analysis and representation theory. We then study recent extensions of the theory which apply to the a class of Poisson manifolds, the b-symplectic manifolds, when equipped with Hamiltonian torus actions.
