摘要

The product of two modal logics L_1 and L_2 is the modal logic determined by the class of frames of the form f×O such that f and O validate L_1 and L_2, respectively. This paper proves the decidability of the product of converse PDL and polymodal K. Decidability results for products of modal logics of knowledge as well as temporal logics And polymodal K are discussed. All those products form rather expressive but still decidable fragments of modal Predictate logics. Based on the equivalence of polymodal K and the description logic ALL we shall discuss the Fragments obtained, extend the expressive power a bit, and compare them with other modal description logics.
