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.
