Abstract
In this paper we study the variety of the so-called Burnside ai-semirings. The notion of \((n, m)\)-closed subset of a semigroup is introduced and a model of a free Burnside ai-semiring is given by using the \((n, m)\)-closed subsets of a free Burnside semigroup. Thus some results obtained by Zhao, Kuřil and Polák are generalized and extended.
