Abstract. In this paper we revisit Logic Programming under the answer-set semantics - or Answer-Set Programming - and its extension Evolving Logic Programming, two languages that u...
The satisfiability and finite satisfiability problems for the two-variable fragment of first-order logic with counting were shown in [5] to be in NExpTime. This paper presents ...
We consider two recently proposed definitions of the expressive power of description logics, one due to Baader, the other due to Kurtonina and de Rijke. The proposals are non-equi...
We consider an extension of the guarded fragment in which one can guard quantiers using the transitive closure of some binary relations. The obtained logic captures the guarded fr...
This paper gives an overview of recent results concerning the modular derivation of (i) modal specification logics, (ii) notions of simulation together with logical characterisati...
