Contributions to the theory of set valued functions and set valued measures. (English) Zbl 0634.28004
The author studies measurable multifunctions and multimeasures with values in a Banach space X. He proves a variation of the known Dunford theorem on weak compactness of subsets of the space $$L^ 1(X)$$ and a Dunford-Pettis type theorem for sequences of integrably bounded multifunctions. Next he gives a representation theorem for additive set valued operators defined on $$L^ 1(X)$$ and some pointwise weak compactness results for multifunctions with weakly compact set of Bochner integrable selectors. Finally he determines various properties of transition multimeasures.
