## Abstract The aim of the paper is to give necessary and sufficient conditions under which the set of extreme points of the unit ball of an Orlicz space __L__^ϕ^(μ), equipped with the Luxemburg norm, is closed. Using that description a theorem is given saying when the notions “extremal” and “nice”

In a Hilbert space (H, & } &) is given a dense subspace W and a closed positive semidefinite quadratic form Q on W\_W. Thus W is a Hilbert space with the norm &u& 1 =(&u& 2 +Q(u)) 1Â2 . For any closed subspace D of (W, & } & 1 ) let A(D) denote the selfadjoint operator in the closure of D in H such
