… if $R$ is quasi-projective as an RR-module. As a generalization of Wedderburn’s
structure theorem for semi-simple rings, we shall obtain the following: $R$ is a semi-perfect
h-central ring if and only if $R$ is a direct sum of a finite number of finite dimensional matrix
rings over sum-irreducible h-central rings (Th. In \S 5, we shall generalize the uniqueness …
