چکیده
|
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 {a_α} αϵi is a family f-convex subsets with non empty intersection of a banach space x, then u αϵi aα is f-convex. moreover, we introduce new definition of notion fconvexiy.
