The upcoming talk
At the next session of the TCS,
on the 19th of March 2025,
at 2:15 – 4:15 p.m. CET / 3:15 – 5:15 p.m. EET
Leonid Ryvkin
(ICJ, Université Claude Bernard Lyon 1)
shall talk about
“Introduction to singular foliations“.
Abstract
A singular foliation can be seen as an involutive collection of vector fields on a smooth manifold. When the span of these vector fields has the same dimension everywhere, the foliation is called regular. In this talk, we will discuss the properties of singular foliations, when no assumption about regularity is given. We will see that interesting phenomena can already be observed locally, and introduce some basic algebraic tools which are useful for their study.
