Structure of long idempotent-sum free sequences over finite cyclic semigroups

Guoqing Wang

Let $S$ be a finite cyclic semigroup written additively. An element $e$ of $S$ is said to be idempotent if $e + e = e$ . A sequence $T$ over $S$ is called…

Existence of Erdős-Burgess constant in commutative rings

Guoqing Wang

Let $R$ be a commutative unitary ring. An idempotent in $R$ is an element $e \in R$ with $e^{2} = e$ . The Erdős-Burgess constant associated with the ring $R$ is the smallest positive in…

Lower bound for the Erdős-Burgess constant of finite commutative rings

Guoqing Wang

Let $R$ be a finite commutative unitary ring. An idempotent in $R$ is an element $e \in R$ with $e^{2} = e$ . The Erdős-Burgess constant associated with the ring $R$ is the smallest posi…
