Additive Fluents
We propose a situation calculus formalization of action domains that include numeric-valued fluents (so-called additive or measure fluents) and concurrency. Our approach allows fo...

Verified Optimizations for the Intel IA-64 Architecture
This paper outlines a formal model of the Intel IA-64 architecture, and explains how this model can be used to verify the correctness of assembly-level code optimizations. The form...

The Railroad Crossing Problem: An Experiment with Instantaneous Actions and Immediate Reactions
We give an evolving algebra solution for the well-known railroad crossing problem and use the occasion to experiment with agents that perform instantaneous actions in continuous t...

Games and Definability for System F
We present a game-theoretic model of the polymorphic -calculus, system F, as a fibred category. Every morphism of the model defines an -expanded, -normal form ^ of system F whose...

Structural Cut Elimination
We present new proofs of cut elimination for intuitionistic, classical, and linear sequent calculi. In all cases the proofs proceed by three nested structural inductions, avoiding...
