This volume contains 37 invited research papers collected in memory of Dieter Rodding, who is known for his work on the classification of recursive functions, on reduction classes, on the spectrum problem and on the complexity of cardinality quantifiers in predicate logic and in arithmetical hierarchy. He was one of the first to pursue the interaction of logic and computer science. The volume reflects the wide spectrum of Dieter Rodding's scientific interests."

This volume contains the final versions of a collection of papers presented at the Annual Conference of the European Association for Computer Science Logic, CSL '93, held at Swansea, UK in September 1993.
The 21 full papers included were selected from a total of 62 submissions and essentially contribute to the whole area of computer science logic research. They are devoted to such topics as set constraints, lambda calculi, process algebras, program semantics, intuitionistic logics, fixed-point logics, the equivalence problem, Horn clauses, quantifiers, and proof tranformations.
