In this paper we prove a representation result for essentially bounded multivalued martingales with nonempty closed convex and bounded values in a real separable Banach space. Then we turn our attention to the interplay between multimeasures and multivalued Riesz representations. Finally, we give the multivalued Radon-Nikodym property.
Sia $X$ uno spazio di Banach reale, separabile e $\mathcal{K}_{c}(X)$ la classe dei sottoinsiemi non vuoti, chiusi, limitati e convessi di $X$. Si dimostra un risultato di rappresentazione per martingale essenzialmente limitate a valori in $\mathcal{K}_{c}(X)$. Quindi rivolgiamo la nostra attenzione al legame tra misure multivoche e rappresentazioni di Riesz a valori multivoci. Infine, diamo la versione multivoca del teorema di Radon-Nikodym.
