Semi-decidable Synthesis for Triangular Hybrid Systems
Abstract. The algorithmic design of least restrictive controllers for hybrid systems that satisfy reachability specifications has received much attention recently. Despite the imp...

Hybrid Systems with Finite Bisimulations
Abstract. The theory of formal verification is one of the main approaches to hybrid system analysis. Decidability questions for verification algorithms are obtained by constructi...

A Logical Approach to Decidability of Hierarchies of Regular Star-Free Languages
We propose a new, logical, approach to the decidability problem for the Straubing and Brzozowski hierarchies based on the preservation theorems from model theory, on a theorem of ...

On the Modularity of Deciding Call-by-Need
In a recent paper we introduced a new framework for the study of call by need computations. Using elementary tree automata techniques and ground tree transducers we obtained simple...

On the Decidability of Containment of Recursive Datalog Queries - Preliminary report
The problem of deciding query containment has important applications in classical query optimization and heterogeneous database systems. Query containment is undecidable for unres...
