Research Abstract

About matrix coefficients of semi-simple Lie groups, we obtained a more precise result for the middle discrete series of SU(2, 2) about the asymptotic expansion. We investigated the explicit formula of the matrix coefficients of SU(3, 1)(both are joint works together with T. Hayata and H. Koseki). Utilizing the asymptotic expansion, we obtained the explicit formula of the c-functions of certain P_J-principal series representations of Sp(2, R) explicitly(joint work with M. Iida). We push forward the investigation of 0-cells of the fundamental domain of the Siegel modular group of genus 2.
