Abstract.

We investigate the indecomposable direct summands of a product of modules¶\( \prod_{i \in I} M_i \) by studying categorical properties of \( {\cal M} = {M_i | i \in I} \)¶ as well as module-theoretical properties of \( M = \coprod_{i \in I} M_i \) viewed as module¶ over its endomorphism ring.
