内容简介:Let Pi be a simple supercuspidal representation of the quasi-split unramified even unitary group with respect to an unramified quadratic extension E/F of p-adic fields. We compute the Rankin-Selberg gamma factor for rank-1 twists of Pi by a tamely ramified character of E*. For non-dyadic cases, the gamma factor can also be recovered by considering the endoscopic lift of the representation. For the dyadic case, the result is original and we expect to extend the results on the Langlands parameter of the simple supercuspidal representations to the dyadic case with our computation.
