In particular, we will show how it is possible to represent and logically formalize reasoning about classes of measures such as probabilities, plausibility, possibilities and necessities over several classes of many-valued events. Fuzzy logics provide a powerful framework to handle and combine fuzziness and uncertainty. Indeed, in such logics the operations associated to the evaluation of the connectives are functions defined over the real unit interval [0, 1], that correspond, directly or up to some combinations, to operations used to compute degrees of uncertainty. Then, such algebraic operations can be embedded in the connectives of the many-valued logical framework, resulting in clear and elegant formalizations.}, ISBN = {978-1-84890-037-0}, author = {Tommaso Flaminio and Llu\'{\i}s Godo and Enrico Marchioni} }
