Lucio Cirio (SISSA, Trieste):
Drinfeld twists and noncommutative
equivariant cohomology
In this talk I will construct Weil and Cartan models for the
equivariant cohomology associated to covariant actions of twisted Hopf
algebras on noncommutative spaces. The main idea will be to implement
a Drinfeld twist to the noncommutative Weil algebra introduced by
Alekseev and Meinrenken.
