摘　　要：该文证明了对于一般的 M∈ R(Γ ) ,M( x) =J1;m Jq;m在 R(Γ )中存在始于 (终于 ) M的左 (右 )Bocs was introduced by Rojter in 1975 and d eveloped by Drozd in 1977.From this relation Drozd proved one of the most import ant theorem in representation theory of algebra.Namely a finitely dimensional K -algebra is either of representation tame type or of representation wild type.B autista,Kleiner,Burt and Butler solved the existence problem of almost split seq uences in the representation category of a bocs.This paper provides a constructi on of almost split sequences with a specific example.

关 键 词：BOCS 几乎可裂序列(左或右)
