Abstract
A necessary and sufficient condition on a local ring over which all indecomposable finite-dimensional algebras are local is found. The Krull―Schmidt theorem for a class of rings that includes both the Henselian valuation rings and the rings of integers of multidimensional fields is proved. Bibliography: 2 titles.
