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...
Abstract. This paper studies the expressive power of finite-state automata recognizing sets of real numbers encoded positionally. It is known that the sets that are definable in th...
We explore the expressive power of a recently developed qualitative region-based geometry and apply it to the problem of representing and reasoning about the motion of rigid bodie...
