An observation on factorizations of finite groups

George M. Bergman

Given a finite group $G$ and a factorization of its order, $∣ G ∣ = a_{1} a_{2},$ we show that a sufficient condition for there to exist subsets $A_{1}, A_{2} \subseteq G$ such that $|A_1| =…

Criteria for existence of semigroup homomorphisms and projective rank functions

George M. Bergman

Let $P,$ $S,$ and $T$ be semigroups, $f : P \to S$ and $g : P \to T$ semigroup homomorphisms, and $X$ a generating set for $S$ (possibly infinite). Clearly, a <i>necessary</i> condition…
