Abstract:

For a given inverse semigroup S, we introduce the notion of algebraic crossed product by using a given partial action of S, and we will prove that under some condition it is associative. Also we will introduce the concept of partial semigroup algebra K_Par(S), and we show that the suitable quotient of K_Par(S) is a kind of crossed product.
