All major semantics of normal logic programs and normal logic programs with aggregates can be described as fixpoints of the one-step provability operator or of operators that can...
The new generic scheme CFLP(D) has been recently proposed in [24] as a logical and semantic framework for lazy constraint functional logic programming over a parametrically given ...
Abstract. We introduce a logical language with nullary operators min(n), for each non-negative integer n, which mean `the reasoner has at least n different beliefs'. The resul...
We introduce a temporal logic TAL and prove that it has several nice features. The formalism is a two-dimensional modal system in the sense that formulas of the language are evalua...
Abstract. Security properties are profitably expressed using notions of contextual equivalence, and logical relations are a powerful proof technique to establish contextual equiva...
