formal matrix ring; bimodule; system of factors; Wedderburn-Artin theorem
Summary:
We investigate the formal matrix ring over $R$ defined by a certain system of factors. We give a method for constructing formal matrix rings from non-negative integer matrices. We also show that the principal factor matrix of a binary system of factors determine the structure of the system.
