“…An important key ingredient in such a decomposition is the existence of selections "integrable in the same sense" as the corresponding multifunction. The existence of scalarly measurable selections of arbitrary weakly compact valued scalarly measurable multifunctions has been showed by Cascales, Kadets and Rodriguez in [11].…”
Integral properties of multifunctions with closed convex values are studied. In this more general framework not all the tools and the technique used for weakly compact convex valued multifunctions work. We prove that positive Denjoy-Pettis integrable multifunctions are Pettis integrable and we obtain a full description of McShane integrability in terms of Henstock and Pettis integrability, finishing the problem started by Fremlin [23].

“…Let G : Ω → F (X) be any scalarly measurable fuzzy mapping that is dominated by Γ . Then, for each r ∈ (0, 1], the multifunction G r has scalarly measurable selections (see [9]). It follows by the hypothesis that each scalarly measurable selection of G r is Pettis integrable.…”

“…control theory, optimization or mathematical economics), a wide theory was developed for set-valued integrability in separable Banach spaces (see [1], [6], [18] and reference inside, [12,13], [15], [20]). Recently several authors studied set-valued integrability without separability assumptions in Banach spaces (see [2], [3], [5] [7,9], [10], [14] and [22]). It is well known the useful role played by fuzzy mappings in the theory of fuzzy sets and their applications.…”
In this paper we study the Pettis integral of fuzzy mappings in arbitrary Banach spaces. We present some properties of the Pettis integral of fuzzy mappings and we give conditions under which a scalarly integrable fuzzy mapping is Pettis integrable.Cordially dedicated to Professor Paolo de Lucia on the occasion of his 80-th birthday with esteem and admiration 2010 Mathematics Subject Classification.

“…The choice to deal with these types of integration is motivated by the fact that Bochner integrability of selections is a strong condition; moreover selection theorems for the Auman-Bochner integral are stated in the separable context. In order to overcome this problem contributions have been given also in [16,17,21,22].…”

“…A very important tool for the study of set-valued integration is the Kuratowski and Ryll-Nardzewski's theorem which guarantees the existence of measurable selectors, though it has the handicap of the requirement of separability for the range space. Recently this result was extended to the non separable case in [16,17,24] for other kinds of multivalued integrals or for the ck(X)-valued case, while here a selection theorem is given for cwk(X)-valued, H-integrable multifunctions.…”
Henstock-type integrals are considered, for multifunctions taking values in the family of weakly compact and convex subsets of a Banach lattice X. The main tool to handle the multivalued case is a Rådström-type embedding theorem established by C. C. A. Labuschagne, A. L. Pinchuck, C. J. van Alten in 2007. In this way the norm and order integrals reduce to that of a single-valued function taking values in an M -space, and new proofs are deduced for some decomposition results recently stated in two recent papers by Di Piazza and Musia l based on the existence of integrable selections.
