We study possible formulations of algebraic propositional proof systems operating with noncommutative formulas. We observe that a simple formulation gives rise to systems at least ...
We describe a system for the automated certification of safety properties of NASA software. The system uses Hoare-style program verification technology to generate proof obligatio...
We present a coinductive proof system for bisimilarity in transition systems specifiable in the de Simone SOS format. Our coinduction is incremental, in that it allows building in...
