A multivalued version of the Radon-Nikodym theorem, via the single-valued Gould integral

Some topics concerning the Gould integral are presented here: new results of integrability on finite measure spaces with values in an M-space are given, together with a Radon-Nikodym theorem relative to a Gould-type integral of real functions with respect to a multisubmeasure.Comment: 19 page
