Distinction and Asai -functions for generic representations of general linear groups over p-adic fields
arXiv:0902.3061
Abstract
Let be a quadratic extension of -adic fields, and a positive integer. A smooth irreducible representation of the group is said to be distinguished, if it admits on its space a nonzero -invariant linear form. In the present work, we classify genric distinguished representations of the group in terms of inducing quasi-square-integrable representations. This has as a consequence the truth of the expected equality between the Rankin-Selberg type Asai -function of a generic representation, and the Asai -function of its Langlands parameter.
