Abstract

Using the notions of Topological dynamics, H. Furstenberg defined central sets and proved the Central Sets Theorem. Later V. Bergelson and N. Hindman characterized central sets in terms of algebra of the Stone-\v{C}ech Compactification of discrete semigroup. They found that central sets are the members of the minimal idempotents of βS\beta S, the Stone-\v{C}ech Compactification of a semigroup (S,)\left(S,\cdot\right). We know that any closed subsemigroup of βS\beta S is generated by a filter. We call a set AA to be a F\mathcal{F}-central set if it is a member of a minimal idempotent of a closed subsemigroup of βS\beta S, generated by the filter F\mathcal{F}. In this article we will characterize the F\mathcal{F}-central sets dynamically.
