We introduce the notion of arithmetic progression blocks or AP-blocks of Zn, which can be represented as sequences of the form (x, x+m, x+2m,..., x+(i-1)m) (mod n). Then we consider the problem of par...

All rings are assumed to be finite commutative with identity element. An element a \in R is called a regular element if there exists b \in R such that a=a2b, the element b is called a von Neumann inve...
