A Decidable Fragment of Separation Logic
We present a fragment of separation logic oriented to linked lists, and study decision procedures for validity of entailments. The restrictions in the fragment are motivated by the...

Decidability of the Guarded Fragment with the Transitive Closure
We consider an extension of the guarded fragment in which one can guard quantiers using the transitive closure of some binary relations. The obtained logic captures the guarded fr...

Deciding Termination of Query Evaluation in Transitive-Closure Logics for Constraint Databases
We study extensions of first-order logic over the reals with different types of transitive-closure operators as query languages for constraint databases that can be described by...

The Boundary Between Decidability and Undecidability for Transitive-Closure Logics
To reason effectively about programs, it is important to have some version of a transitive-closure operator so that we can describe such notions as the set of nodes reachable from ...
