表示论中的覆盖已经被BongartzGabriel [2],Gabriel [3],绿色[4],Riedtman [6,7]成功地使用。特别重要的是研究Auslander-Reiten的覆盖物和普通的覆盖物之间的关系。在这个方向上,P.加布里埃尔提出,在第三届国际会议上表示的代数,普埃布拉M6 xico,1980年,以下猜想:“设g是一个自同构的代数A的有限表示型。对于每个右模M,用Mg表示具有基础群M和标量乘(m,2)~mgl(2)的A-模。如果对每个单S,Sgq~S,则对每个不可分解的M”,M g q~ M。本说明的目的是对这一说法给出一个简短的证明。该猜想对无限表示型代数不成立。康-
Coverings in representation theory have been successfully used by: BongartzGabriel [2], Gabriel [3], Green [4], Riedtman [6, 7]. Of particular importance is the study of the relations between the coverings of the Auslander-Reiten quiver and the ordinary quiver. In this direction P. Gabriel posed, in the Third International Conference on Representations of Algebras, Puebla M6xico, 1980, the following conjecture: "Let g be an automorphism of an algebra A of finite representation type. For each right module M, denote by M g the A-module with underlying group M and scalar multiplication (m, 2 )~mgl (2 ) . If Sgq~S for each simple S, then M g q~ M for each indecomposable M". The aim of this note is to give a short proof of this statement. The conjecture is not true for algebras of infinite representation type. Con-
