The generation of efficient code for Prolog programs requires sophisticated code transformation and optimization systems. Much of the recent work in this area has focussed on hig...
The HOL system is an LCF-style mechanized proof-assistant for conducting proofs in higher order logic. This paper discusses a proposal to extend the primitive basis of the logic un...
We present a bimodal logic suitable for formalizing reasoning about points and sets, and also states of the world and views about them. The most natural interpretation of the logi...
