Abstract |
|
We define a notion of pseudospherical type for smooth representations of the nontrivial two fold central extension of SL2(Q2). We describe completely the irreducible representations that contain the pseudospherical type. We relate our results to Kohnen’s plus and minus spaces of classical modular forms of half integral weight. |
Keywords
