Hi,
What is the statement of the EichlerShimura relation for Shimura curves? And where can one find a proof?
Thanks

In the general case of Shimura curves over totally real number fields, a nice exposition of the EichlerShimura relation is given, for example, in $\S 1.14$ of this article of J. Nekovář, where you can find pointers to the relevant literature (in particular, a standard reference is Carayol's paper mentioned therein).
