Compilation of Query-Rewriting Problems into Tractable Fragments of Propositional Logic
We consider the problem of rewriting a query efficiently using materialized views. In the context of information integration, this problem has received significant attention in th...

The Tractability of Model-Checking for LTL: The Good, the Bad, and the Ugly Fragments
In a seminal paper from 1985, Sistla and Clarke showed that the model-checking problem for Linear Temporal Logic (LTL) is either NP-complete or PSPACE-complete, depending on the se...

The complexity of satisfiability for fragments of hybrid logic - Part I
The satisfiability problem of hybrid logics with the downarrow binder is known to be undecidable. This initiated a research program on decidable and tractable fragments. In this p...
