Abstract

For any arbitrary variety V , the degree dp(V ) of V with respectto proper hypersubstitutions was introduced in [6]. This degree of any varietyof bands was determined in [4]. In this paper we characterize the universe ofthe free algebra of each solid variety of semirings and from this we derive thedegree dp(V ) if V is any solid variety of semirings.
