A proof system for finite trees,aper is to provide it with a sound and complete proof system. We do so using standard axioms from . and ., and prove completeness by extending techniques due to Van Benthem and Meyer-Viol (1994) and Blackburn and Meyer-Viol (1994). We conclude with a proof of the EXPTIME-completeness of the satisfia

Simultaneous rigid E-unification is undecidable,, like the tableau method or the connection method. There were several faulty proofs of the decidability of this problem. We prove the undecidability of simultaneous rigid .-unification using reduction of Hubert‘s tenth problem. As a consequence, we obtain the undecidability of the ∃*-fragment of in

An evolving algebra abstract machine,to the design and analysis of various kinds of discrete dynamic systems. Aiming at the development of a comprehensive EA-based specification and design environment, we introduce the concept of an . as a platform for the systematic development of EA tools; for instance, as required for machine based

,Rewriting with extensional polymorphic λ-calculus,and . types: this system corresponds to the Intuitionistic Positive Calculus with implication, conjunction, quantification over proposition and the constant .. This result is an important step towards a new theory of reduction based on expansion rules, and gives a natural interpretation to the notio

Generalized implicit definitions on finite structures,f a (deterministic) definition. These generalized implicit definitions offer more expressive power than classical implicit definitions. Moreover, their expressive power can be characterized over unordered finite structures in terms of the complexity class NP ∩ co-NP. Finally, we investigate a subcla
