Abstract

Let E be a quadratic semisimple extension of a local field F of characteristic zero. We determine explicit relation between gamma factors for Asai representations of R_E/F\rm GL_2/E defined by the Weil-Deligne representations and local zeta integrals. When E = F× F, the results were due to Henniart and Jacquet. We completed the theory in this article based on explicit calculation.
