 This is just a gentle remainder of our seminar!

> Cohomology in algebra, geometry, physics and statistics
> Wednesday, 4 March 2026 - 13:30 to 14:30
> Place: Institute of Mathematics of ASCR, Žitná 25, Praha 1, the  blue
> lecture  room   +ZOOM meeting

> Speaker: Andrey  Krutov, Mathematical Institute, Charles University
> Title: Non-integrable distributions with simple infinite-dimensional Lie
> superalgebra of symmetries Abstract
>
>
> The only simple infinite-dimensional Lie algebras preserving a
> non-integrable distribution are the algebras of contact vector fields in
> odd dimensions. We formulate analogs of the above statement and prove
> them for (super)varieties over algebraically closed fields of any
> characteristic $p\geq0$.

>
> Over fields~$\mathbb{K}$ of characteristic $p>0$, we classify the
> Weisfeiler gradings (briefly: W-gradings), those corresponding to a
> maximal subalgebra of finite codimension, of the known simple vectorial
> Lie (super)algebras with unconstrained shearing vector of heights of the
> indeterminates, distinguish W-gradings of (super)algebras preserving
> non-integrable distributions.
