The Friday Fish Seminar is a weekly seminar organized by the Poisson Geometry group in Utrecht. Our aim is to provide an opportunity for young mathematicians in the field of Poisson Geometry to present their research and to broaden their network. With this online edition, we hope to complement the Global Poisson Webinar.
- When: Friday 16.00-17.00 (CEST) – participants are very welcome to stay around afterwards for some informal discussion.
- Where: Zoom.
- How: Please send an e-mail to fridayfishseminar[at]gmail.com to receive weekly invitations to the Zoom meetings.
Every first Friday of the month we will have a “Junior Poisson Session”, consisting of two 30-minute talks given by junior members of the Poisson community. Any PhD student or early career postdoc that wishes to give a talk is welcome to register here. Speakers should feel free to talk about work in progress.
Title: Symplectic : Contact = Poisson : Jacobi = Affine : Projective.
Speaker: Daniele Sepe
Date: July 10, 2020
While contact geometry is often described as the odd-dimensional analogue of symplectic geometry, Arnol'd pointed out that the relation between these two geometries is analogous to that between affine and projective geometries. A natural (vague!) question is to investigate the extent to which this analogy extends to the degenerate versions of symplectic and contact structures, namely Poisson and Jacobi geometries.
The aim of this talk is to attempt to formalise the above question and to illustrate the intimate relation between these six geometries through a few specific problems, including isotropic realisations and Poisson/Jacobi manifolds of compact types. The talk is based on joint work with María Amelia Salazar, and on ongoing joint work with Camilo Angulo and María Amelia Salazar.
