## Abstract Sieg and Wegner showed that the stable exact sequences define a maximal exact structure (in the sense of Quillen) in any pre‐abelian category 41. We generalize this result to weakly idempotent complete additive categories.

In the present paper we prove that a certain subcategory C C of the module category over some infinite-dimensional algebra R has almost split sequences and strongly homogeneous property; i.e., for each indecomposable module M in C C, there is an almost split sequence starting and also ending at M. I
