Handbuch der kommunalen Sozialpolitik,yεE we always have dist (y,P.(x))≥‖x−y‖-dist(x,G), we study the subspaces G with the property — which we call property (*) — that this inequality is an equality for each xεE with P.(x)≠φ and each gεG. This property generalizes the notion of semi L-summand studied by A.Lima. For a subspace G with pr

,On Etcheberry’s extended Milutin lemma,onal numbers. Etcheberry proved this by constructing a continuous surjection π: I→X that admits an averaging operator. Here, we provide an alternative technique for the construction of averaging operators that are even regular and also allow one to prove the first mentioned result.
