Resumen de A Künneth Theorem for p-Adic Groups

A. Raghuram

• Let G1 and G2 be p-adic groups. We describe a decomposition of Ext-groups in the category of smooth representations of G1 \times G2 in terms of Ext-groups for G1 and G2. We comment on Ext1G(pi,pi) for a supercuspidal representation pi of a p-adic group G. We also consider an example of identifying the class, in a suitable Ext1, of a Jacquet module of certain representations of p-adic GL2n.
