We define a new action of the symmetric group and its Hecke algebra on polynomial rings whose invariants are exactly the quasi-symmetric polynomials. We interpret this construction in terms of a Demazure character formula for the irreducible polynomial modules of a degenerate quantum group. We use t

In this paper a trace functional is defined for certain algebras of Fourier integral operators (including, for instance, the algebra of Toeplitz operators on the boundary of a strictly pseudoconvex domain) and it is shown that vanishing of this trace characterizes commutators in each of these algebr
