Abstract: Consider the representation correspondence for a reductive dual pair $ ({G_1},{G_2})$ over a finite field. We consider the question of how the correspondence behaves for unipotent representations. In the special case of cuspidal unipotent representations, and a certain fundamental situation, that of "first occurrence", the representation correspondence takes a cuspidal unipotent representation of $ {G_1}$ to one of $ {G_2}$. This should serve as a fundamental case in studying the correspondence in general over both finite and local fields.
