Some Topics in Several Complex Variables

目：Weighed Bergman spaces on Siegel-Jacobi spaces:I. Reproducing kernels and analytic continuation, discrete spectrum of  Laplace operators;II. Bilinear-invariant differential operators.

点：数学院南楼N902

要：In Part I, I'll study weighted Bergman spaces on the Siegel-Jacobi spaces and  their analytic continuation, finding the corresponding Wallach set. We prove that the  Jacobi-group invariant Laplace operator has positive eigenvalues above the zero eigenvalue (whose eigenspace is the weighted Bergman space). In Part II, I'll find a decomposition of tensor-products of the weighted Bergman spaces and the corresponding Rankin-Cohen brackets, generalizing my earlier work with Lizhong Peng.

目：Trace and Dixmier trace of curvature of infinite-dimensional vector bundles

间：07.22（星期三）,09:3011:30

点：数学院南楼N902

要：We construct infinite dimensional vector bundle over the Siegel domain and over the Teichmüller space, and we compute the trace (Dixmier trace) of the curvature operator.
