Program [12] and Abstracts [13] of MPI-Oberseminar

The Oberseminar is a very long running seminar at MPI (‘Ober‘ standing for 'upper'). Its idea is that the guests of the MPI speak in this seminar (hopefully early in their stay) and get the chance to explain their work to the other guests.

Rationality of Fano 3-folds over nonclosed fields [40]

Posted in

Talk [41]

Speaker:

Yuri Prokhorov

Affiliation:

Steklov Mathematical Institute, Moscow/MPIM

Date:

Tue, 2019-08-27 14:00 - 15:00

Location:

MPIM Lecture Hall [4]

Parent event:

Seminar on Algebra, Geometry and Physics [42]

The rationality problem for smooth Fano threefolds over algebraically closed fields is basically solved.
In this talk I will discuss rationality of forms of these Fanos over nonclosed fields of characteristic 0.
I will concentrate on the case where the Picard number equals 1.

The talk is based on joint work with Alexander Kuznetsov (in progress).

Seminar on Algebra, Geometry and Physics [42]

There are many formulas that express interesting properties of a finite group G in terms of sums over its characters. For evaluating or estimating these sums, one of the most salient quantities to understand is the character ratio:

Severin Barmeier

Parent event:

Seminar on Algebra, Geometry and Physics [42]

W. Lowen and M. Van den Bergh developed a deformation theory for Abelian categories, such that deformations of the category of (quasi)coherent sheaves on an affine variety Spec A correspond to deformations of the algebra A, which in turn are controlled by the Hochschild cochain complex equipped with the Gerstenhaber bracket.

Parent event:

Higher Differential Geometry Seminar [46]

The spin groups and the Clifford algebras have played a very important role in Differential Geometry and Physics. In the search for a unified spinorial approach to special Riemannian holonomy, we found a suitable notion for twisted pure spinor which generalizes that of a classical pure spinor developed by Cartan. Along the way, we realized that parallel twisted pure spinors, besides satisfying the corresponding twisted Dirac equation, satisfy a curvature identity analogous to the second Seiberg-Witten equation in 4-dimensions.
