| contents | In this paper, we extend the local Shimura correspondence building upon the groundwork laid by Gordan Savin. As preparations, we review part of the type theory of Bushnell and Kutzko which equally applies to covering groups. By adapting the method of linear algebraic groups, we describe the structure of Hecke algebras associated with genuine principal series components and construct the types. In particular, we show each of them shares the same affine Hecke algebra part as one corresponding Hecke algebra of the principal endoscopy group. However, we give a counter example to show they are not isomorphic in general. |
