Abstract: 

The cubic Dirac operator for a complex semisimple Lie algebra \mathfrak{g} was introduced (in the algebraic setting) by Kostant in 1999. It has numerous applications in representation theory.  In 2000, Alekseev and Meinrenken used it to study equivariant cohomology of G-manifolds.  In this talk we will present a q-deformation of the cubic Dirac operator for \mathfrak{sl}_2.  In particular, we will discuss a possible q-deformation of the noncommutative Weil algebra of \mathfrak{g}.
