We study Aumann-Pettis integrable multifunctions on 2X, where X is a separable Banach space and their integrals. We prove the existence of a weakly compact convex-valued Pettis integrable multifunction F for a closed, convex, decomposable and weakly sequentially compact subset K of P1(μ, X), the space of all Pettis integrable functions on X such that K coincides with SFP, the collection of all Pettis integrable selectors of F. We also study the weak compactness property of SFP.
Keywords: Aumann-Pettis integrable multifunctions, Pettis integrable multifunctions, Aumann-Pettis integral, Pettis integral, weak convergence.
