INTEGRATION FORMULAS AND EXACT CALCULATIONS IN THE CALOGERO-SUTHERLAND MODEL

Some integration formulas which either occur or are implicit in Ha's recent exact calculation of some correlations in the Calogero-Sutherland model are discussed. These integration formulas include the calculation of the inner product [O\rho(O)\kappa] between the density operator acting on an excited state and the ground state, and a generalization of the Selberg integral due to Dotsenko and Fateev.
