A Deductive System for FO(ID) Based on Least Fixpoint Logic
Abstract. The logic FO(ID) uses ideas from the field of logic programming to extend first order logic with non-monotone inductive definitions. The goal of this paper is to exten...

On the Union of Cylinders in Three Dimensions
We show that the combinatorial complexity of the union of n infinite cylinders in R3 , having arbitrary radii, is O(n2+ε ), for any ε > 0; the bound is almost tight in the w...

Half-Order Modal Logic: How to Prove Real-Time Properties
Abstract. We introduce a novel extension of propositional modal logic that is interpreted over Kripke structures in which a value is associated with every possible world. These val...

Context-Sensitive Languages, Rational Graphs and Determinism
We investigate families of infinite automata for context-sensitive languages. An infinite automaton is an infinite labeled graph with two sets of initial and final vertices. Its la...

Choice in Dynamic Linking
We introduce a computational interpretation for Hilbert’s choice operator (ε). This interpretation yields a typed foundation for dynamic linking in software systems. The use of ...
