On Slicewise Monotone Parameterized Problems and Optimal Proof Systems for TAUT
Abstract. For a reasonable sound and complete proof calculus for firstorder logic consider the problem to decide, given a sentence of firstorder logic and a natural number n, whet...

Shift Equivalence of P-finite Sequences
We present an algorithm which decides the shift equivalence problem for Pfinite sequences. A sequence is called P-finite if it satisfies a homogeneous linear recurrence equation w...

On the fixed-parameter tractability of the equivalence test of monotone normal forms
We consider the problem Monet—given two monotone formulas ϕ in DNF and ψ in CNF, decide whether they are equivalent. While Monet is probably not coNPhard, it is a long standin...

Fast equivalence-checking for normed context-free processes
Bisimulation equivalence is decidable in polynomial time over normed graphs generated by a context-free grammar. We present a new algorithm, working in time O(n5 ), thus improving...

On the Expressiveness of Infinite Behavior and Name Scoping in Process Calculi
In the literature there are several CCS-like process calculi differing in the constructs for the specification of infinite behavior and in the scoping rules for channel names. In t...
