Order-type Henstock and McShane integrals in Banach lattice setting
We study Henstock-type integrals for functions defined in a compact metric
space endowed with a regular -additive measure , and taking
values in a Banach lattice . In particular, the space with the usual
Lebesgue measure is considered.Comment: 5 page
A note on set-valued Henstock--McShane integral in Banach (lattice) space setting
We study Henstock-type integrals for functions defined in a Radon measure
space and taking values in a Banach lattice . Both the single-valued case
and the multivalued one are considered (in the last case mainly -valued
mappings are discussed). The main tool to handle the multivalued case is a
R{\aa}dstr\"{o}m-type embedding theorem established in [50]: in this way we
reduce the norm-integral to that of a single-valued function taking values in
an -space and we easily obtain new proofs for some decomposition results
recently stated in [33,36], based on the existence of integrable selections.
Also the order-type integral has been studied: for the single-valued case
some basic results from [21] have been recalled, enlightning the differences
with the norm-type integral, specially in the case of -space-valued
functions; as to multivalued mappings, a previous definition ([6]) is restated
in an equivalent way, some selection theorems are obtained, a comparison with
the Aumann integral is given, and decompositions of the previous type are
deduced also in this setting. Finally, some existence results are also
obtained, for functions defined in the real interval .Comment: This work has been modified both as regards the drawing that with
regard to the assumptions. A new version is contained in the paper
