Abstract

In this paper we establish the endoscopic classification of tempered\nrepresentations of quasi-split unitary groups over local fields, and the\nendoscopic classification of the discrete automorphic spectrum of quasi-split\nunitary groups over global number fields. The method is analogous to the work\nof Arthur on orthogonal and symplectic groups, based on the theory of endoscopy\nand the comparison of trace formulas on unitary groups and general linear\ngroups.\n
