Automorphisms of Zero Divisor Graphs of Galois Rings

Mude, Hussein L; Owino, Maurice O; Ojiema, Michael O (2019)

Let R be a commutative finite ring with unity and let Z(R) be its set of zero divisors. The study of R in which the subset of zero divi sors forms a unique maximal ideal has been extensively done yielding interesting and ...
Unit Groups of Some Classes of Power Four Radical Zero Commutative Completely Primary Finite Rings

Owino, Maurice O; Ojiema, Michael O (2014)

Let R be a completely primary finite ring and J be its Jacobson radical. A class of such rings in which J4 = (0), J3 = (0) has been constructed. Moreover, the structures of their groups of units have been determined ...
