Kodissipative Metrische Projektionen in Normierten Linearen R?umenLet H be a real inner product space with inner product <.,.>. For any subset K of H the metric projection P.:H → P(K) is monotone, i.e., for any (x,k), (x’,k’) ∈P. < k-k’,x-x’ > ≥ 0. This property is used to characterize closed convex sets in Hilbert space.
