【求助】请教三个问题 1 Assume that $A$ is a finite dimensional $K$-algebra，and $M$ a finitely generated indecomposable module, then the socle $socM $ of $M$ is simple，why? 2 Assume that $A$ is a finite dimensional $K$-algebra，and $M$ a finitely generated module, is the injective envelope of $M$ finitely generated? why? 3 Assume that $A$ is a finite dimensional $K$-algebra，and $M$ a finitely generated indecomposable module, is the injective envelope of $M$ indecomposable? why?
