Resumen inglés | Let 0 → ∏ÀI Mα ¾λ→ ∏I Mα ¾γ→ Coker λ → 0 be an exact sequence of modules, in which À is an infinite cardinal, λ the natural injection and γ the natural surjection. In this paper, the conditions are given mainly in the four theorems so that λ (γ respectively) is split or locally split. Consequently, some known results are generalized. In particular, Theorem 1 of [7] and Theorem 1.6 of [5] are improved. |
