COLOQUIOS DEL DEPARTAMENTO DE MATEMATICA

Hoy Jueves 11 de octubre a las 16 hs, Aula E24 - Pab I

FRANÇOIS DUMAS
Université Blaise Pascal, Clermont-Ferrand, Francia.

Título: Noncommutative rational invariants

Resumen:
The talk is a survey on various problems related to the algebraic
structure of the skewfield of invariants $F^G$, where $F$ is the field
of fractions of some noncommutative ring of differential polynomials
$R$ with coefficients in a ring $K$, and $G$ is a group of
automorphisms of $R$ stabilizing $K$.
The main applications concern the Noether's problem for Weyl algebras,
the differential operators on Kleinian surfaces, the algebraic
description of subextensions of Weyl skewfields, and the
noncommutative structures on some spaces of modular forms.

Están todos cordialmente invitados. Los esperamos el jueves!!
