Decidability and Undecidability Results for Nelson-Oppen and Rewrite-Based Decision Procedures
Abstract. In the context of combinations of theories with disjoint signatures, we classify the component theories according to the decidability of constraint satisability problems ...

Undecidability in the Homomorphic Quasiorder of Finite Labeled Forests
Abstract. We prove that the homomorphic quasiorder of finite k-labeled forests has undecidable elementary theory for k 3, in contrast to the known decidability result for k = 2. W...
