Finite Rings in Which 1 is a Sum of Two Non-P-Th Power Units
Published online by Cambridge University Press: 20 November 2018
Extract
Let R be a finite ring with 1 and let R* denote the group of units of R. Let p be a prime number. In this paper we consider the question of whether there exist a, b in R* such that a and b are non- p -th powers whose sum is 1. If such units a, b existing, we say that R is an N (p)-ring. Of course if p does not divide |R*|, the order of R*, then every element in R* is a pth power.
