We consider two kinds of problems: the computation of polynomial and rational solutions of linear recurrences with coefficients that are polynomials with integer coefficients; ind...
For a finite set Γ of Boolean relations, Max Ones SAT(Γ) and Exact Ones SAT(Γ) are generalized satisfiability problems where every constraint relation is from Γ, and the task...
We study type systems for termination in the π-calculus from the point of view of type inference. We analyse four systems by Deng and Sangiorgi. We show that inference can be done...

We show that unless P=NP, there exists no polynomial time (or even pseudo-polynomial time) algorithm that can decide whether a multivariate polynomial of degree four (or higher ev...

Abstract. Interest in role-based access control has generated considerable research activity in recent years. A number of interesting problems related to the well known set cover p...
