DESCRIPTION:We study the notion of semiselectiviy for coideals of the spac
 e of infinite sets of natural numbers\, and propose a generalization to ab
 stract Ramsey spaces. We also consider the corresponding forcing notions. 
 Abstract Ramsey spaces in the sense of  Todorcevic [1] provide a general f
 ramework that unifies several Ramsey type results.\n\n[1] Todorcevic\, S.
