D. Harmanec et al., MODAL LOGIC INTERPRETATION OF DEMPSTER-SHAFER THEORY - AN INFINITE CASE, International journal of approximate reasoning, 14(2-3), 1996, pp. 81-93
A modal logic interpretation of belief and plausibility measures defin
ed on infinite sets is established As a special case, a modal logic in
terpretation of necessity and possibility measures defined on infinite
sets is also established It is proven in both cases that the interpre
tation is complete. These results establish, in effect, modal logic in
terpretations of the Dempster-Shafer theory and possibility theory.
