Semicentral idempotents of upper triangular matrix rings
Journal of Algebra and Its ApplicationsIn this paper, we describe the necessary and sufficient conditions for upper triangular [Formula: see text] matrix over a ring to be left (right) semicentral idempotent. Circle compositions of left and right semicentral idempotent matrices ([Formula: see text]) are considered. Many researchers deal with the problems of expressing various matrices as a
