 This is just a remainder of our seminar for today!

> Cohomology in algebra, geometry, physics and statistics
> Wednesday, 29 May 2024 - 13:30 to 14:30
> Place: Institute of Mathematics of ASCR, Žitná 25, Praha 1, the  blue
> lecture  room of the rear  building+ ZOOM meeting
>
> Speaker: Alexei  Kovalev, Cambridge University
> Title: On nearly parallel G_2-manifolds
> Abstract
>
>
> A nearly parallel G_2-structure on a 7-manifold can be given by a 3-form
>
>
> φ of special algebraic type satisfying a differential equation
>
> dφ = τ* φ for a non-zero constant τ. We consider
>
> nearly parallel G_2-structures on the Aloff--Wallach spaces and
>
> on regular Sasaki--Einstein 7-manifolds. We give a construction and
>
> explicit examples of associative 3-folds (a particular type of minimal
>
> submanifolds) in these spaces.
>
> Joint work with M. Fernández, A. Fino, and V. Muñoz.
