Opis

This volume contains the proceedings of an international conference on rewriting techniques and applications, designed for researchers and lecturers in theoretical computer science and mathematics. It includes 40 papers on a wide variety of topics including term rewriting systems, equational unification, algebraic rewriting, termination proofs, generalization problems, undecidable properties, parametrized specification, normalizing systems, program transformation, query optimization, tree languages, graph languages, theorem proving systems, completion, graph rewriting systems and open problems.
