Hi,


What is the statement of the Eichler-Shimura relation for Shimura curves? And where
can one find a proof?


Thanks



Eichler-Shimura for Shimura curves
In the general case of Shimura curves over totally real number fields, a nice exposition of the Eichler-Shimura relation is given, for example, in $\S 1.14$ of [this article](http://people.math.jussieu.fr/~nekovar/pu/euler.pdf) of J. Nekovář, where you can find pointers to the relevant literature (in particular, a standard reference is Carayol's paper mentioned therein).
