Kodissipative Metrische Projektionen in Normierten Linearen RäumenLet 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.

Kernel Operatorsfrom L. to L. (1<p≤∞) is a kernel operator (for the special case of Lebesgue measure in the real line due to N. Dunford, 1936); in Buhvalov’s approach this corollary is proved first and the other abovementioned results are derived from it.
