The last section calculates a generating function for the elliptic genera of symmetric products. This generalizes the classical results of Macdonald and Zagier.LaTeX, 20 pagesAlgebraic GeometryPrimary 58J26, secondary 11F, 14J, 14MElliptic Genera of singular varieties, orbifold elliptic genus and chiral deRham complextext
