Products of idempotents in regular rings II [PDF]
, 1987 This paper characterizes products of idempotents in (von Neumann) regular rings which are unit-regular or right self-injective. For unit-regular rings, the minimum number of idempotents needed in such a product is determined, thereby generalizing a

Idempotents in symmetric semigroups
Journal of Combinatorial Theory, Series A, 1972 AbstractWe count the number of idempotent elements in a certain section of the s symmetric semigroup Sn on n letters. As a corollary of our result we have that every maximal principal right ideal of Sn contains ∑i=1n−1in−i−1(n−2i−1)+(n−1i) idempotent elements.
