[PHK_seminar] [Cohomology]Wednesday 15 Apr, Alexei Kotov

[Petr Somberg]

 This is just the reminder of our seminar today, 13.30!

----------------------------------------------------------------------

> Cohomology in algebra, geometry, physics and statistics
> Wednesday, 15 April 2026 - 13:30 to 14:30
> Place: Institute of Mathematics of ASCR, Žitná 25, Praha 1, the  blue
> lecture  room +ZOOM meeting
>
> Speaker: Alexei Kotov, University of Hradec Kralove
> Title: Geometry through the Lens of dg Manifolds
> Abstract
> Differential graded (dg) manifolds, or $Q$-manifolds, provide a powerful
> framework for unifying diverse structures in modern geometry. By equipping
> a graded supermanifold with an odd homological vector field $Q$
> (satisfying $Q^2 = 0$), we obtain a robust language
> capable of "taming" complex geometric problems. In this talk, I will
> demonstrate the versatility of the dg-framework by exploring its
> underlying geometry and its applications across several domains,
> specifically focusing on how it characterizes complex structures and
> foliations.
