a celebrated result of i. schur asserts that the derived subgroup of a group is finite provided the group modulo its center is finite, a result that has been the source of many investigations within the theory of groups. in this paper we exhibit a similar result to schur's theorem for vector spaces, acted upon by certain groups. the proof of this analogous result depends on the characteristic o...

We investigate the irreducible cuspidal $C$-representations of a reductive $p$-adic group $G$ over field $C$ characteristic different from $p$. When is algebraically closed, for many groups $G$, list $C$-types $(J,\lambda)$ has been produced satisfying exhaustion, sometimes restricted kind representations, and often unicity. verify that those lists Aut($C$)-stability we produce similar when no ...
