A Descent Criterion for Isobaric Representations
نویسندگان
چکیده
This will appear as an appendix to the paper Functoriality for the exterior square of GL4 and the symmetric fourth of GL2 ([K]) by Henry Kim. The object here is to prove the following extension (from cuspidal) to isobaric automorphic representations of Proposition 3.6.1 of [Ra], which was itself an extension to GL(n) of the Proposition 4.2 (for GL(2)) in [BR]. The argument is essentially the same as in [Ra], but requires some delicate bookkeeping.

On descent for coalgebras and type transformations
We find a criterion for a morphism of coalgebras over a Barr-exact category to be effective descent and determine (effective) descent morphisms for coalgebras over toposes in some cases. Also, we study some exactness properties of endofunctors of arbitrary categories in connection with natural transformations between them as well as those of functors that these transformations induce between co...
متن کاملA Cuspidality Criterion for the Exterior Square Transfer of Cusp Forms on Gl(4)
For a cuspidal automorphic representation Π of GL(4, A), H. Kim proved that the exterior square transfer ∧Π is nearly an isobaric automorphic representation of GL(6, A). In this paper we characterize those representations Π for which ∧Π is cuspidal.

Together with Cogdell, Piatetski-Shapiro and Shahidi, we proved earlier the existence of a weak functorial lift of a generic cuspidal representation of SO2n+1 to GL2n. Recently, Ginzburg, Rallis and Soudry obtained a more precise form of the lift using their integral representation technique, namely, the lift is an isobaric sum of cuspidal representations of GLni (more precisely, cuspidal repre...
متن کاملOn the cuspidality criterion for the Asai transfer to GL(4)
Let F be a number field and K a quadratic algebra over F , i.e., either F × F or a quadratic field extension of F . Denote by G the F -group defined by GL(2)/K. Then, given any cuspidal automorphic representation π of G(AF ), one has (cf. [8], [9]) a transfer to an isobaric automorphic representation Π of GL4(AF ) corresponding to the L-homomorphism LG → LGL(4). Usually, Π is called the Rankin-...
