Abstract Let ${{G}_{1}}$ and ${{G}_{2}}$ be $p$ -adic groups. We describe a decomposition of Ext-groups in the category of smooth representations of ${{G}_{1}} imes {{G}_{2}}$ in terms of Ext-groups for ${{G}_{1}}$ and ${{G}_{2}}$ . We comment on $ ext{Ext}_{G}^{1}left( pi ,pi
ight)$ for a supercuspidal representation $pi$ of a $p$ -adic group $G$ . We also consider an example of identifying the class, in a suitable $E ext{x}{{ ext{t}}^{1}}$ , of a Jacquet module of certain representations of $p$ -adic $ ext{G}{{ ext{L}}_{2n}}$ .
