Abstract

A q-integral over an order polytope coming from a poset is interpreted as a generating function of linear extensions of the poset. As an application, the q-beta integral and a q-analog of Dirichlet's integral are computed. A combinatorial interpretation of a q-Selberg integral is also obtained.
