Abstract :
We use of two notions functionally convex (briefly, F–convex)
and functionally closed (briefly, F–closed) in functional analysis
and obtain more results. We show that if fAg2I is a family F–
convex subsets with non empty intersection of a Banach space
X, then ∪ 2I A is F–convex. Moreover, we introduce new definition
of notion F–convexiy
