Computation Theory and Logic

This volume contains 37 invited research papers collected in memory of Dieter Rِdding, 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 Rِddings scientific interests.
