Popis: In this article, we give a group cohomological interpretation to the Eichler–Shimura isomorphism. For any quaternion algebra A over a totally real field with multiplicative group G , we interpret a weight ( k 1 , k 2 , ⋯ , k d ) -automorphic form of G as a G ( F ) -invariant homomorphism of ( G ∞ , K ∞ ) -modules. Then the Eichler–Shimura isomorphism is given by the connection morphism provided by the natural exact sequences defining the ( G ∞ , K ∞ ) -module of discrete series of weight ( k 1 , k 2 , ⋯ , k d ) .
