Abstract

We prove Jiang's conjecture (1996) to show the existence of an L-function of a cuspidal representation of GSp(4,𝔸) × GSp(4,𝔸) which has a pole of order 2 at s = 1, even for globally generic representations. Moreover, we show that if a cuspidal representation π of GSp(4,𝔸) comes from GSO(4,𝔸), then π is the Weil transfer of Π1 ⊗ Π2 realized as a representation of GSO(4,𝔸) where the Πi are irreducible automorphic cuspidal representations of GL(2,𝔸). This agrees with the Langlands functoriality principle as GSO(4,𝔸) is an endoscopic group for GSp(4,𝔸).

This paper is a part of my thesis at Purdue with supervising of Freydoon Shahidi. I would like to thank him for many helpful discussions.
