摘  要:For any two elements y/le w in a Weyl group let P_{y,w} be the polynomial defined by Kazhdan and the speaker which measures the singularities of the Schubert variety corresponding to w.In this talk (based on joint work with Vogan) I define, assuming that y w are involutions, a new polynomial P_{y,w}^/sigma whose i-th coefficient is a_i-b_i where the i-th coefficient of P_{y,w} is a_i+b_i (a_i,b_i are natural numbers). These new polynomials are of interest in the theory of unitary representations of complex reductive groups. I will also present an algorithm for computing these polynomials.
