We give an AC0 upper bound on the complexity of rst-oder queries over (in nite) databases de ned by restricted linear constraints. This result enables us to deduce the non-expressi...
Abstract. This paper presents new results on the decidability of inductive validity of conjectures. For these results, a class of term rewrite systems (TRSs) with built-in linear i...
There are syntactically identifiable situations in which reduction does not occur in chain format linear deduction systems, i.e. situations in which linear-input subdeductions are ...
We study the complexity of satisfiability and model-checking of the linear-time temporal logic with past (pltl). More precisely, we consider several fragments of pltl, depending o...
We study the notion of solvability in the resource calculus, an extension of the -calculus modelling resource consumption. Since this calculus is non-deterministic, two different ...
