Unit Groups of Classes of Five Radical Zero Commutative Completely Primary Finite Rings
Abstract
In this paper, R is considered a completely primary finite ring and Z(R) is its subset of all zero\xa0divisors (including zero), forming a unique maximal ideal. We give a construction of R whose\xa0subset of zero divisors Z(R) satisfies the conditions (Z(R))5 = (0); (Z(R))4 ΜΈ= (0) and determine\xa0the structures of the unit groups of R for all its characteristics.
