An element in a ring R with identity is said to be strongly nil clean if it is the sum of an idempotent and a nilpotent that commute. R is said to be strongly nil clean if every element of R is strongly nil clean. Let C(R) be the center of a ring R and g(x) be a fixed polynomial in C(R)[x]. Then R is said to be strongly g(x)-nil clean if every element in R is a sum of a nilpotent and ... https://www.greenresourcesredux.com/product-category/brooms-dustpans/
