d Abstract) Thomas Schwentick and Thomas Zeume TU Dortmund University The finite satisfiability problem for two-variable logic over structures with unary relations and two order re...
A modelling language can be defined by a metamodel in UML class diagram. This paper defines the semantics of such metamodels through two mappings: a signature mapping from metamod...
Abstract. In functional programming languages the use of infinite structures is common practice. For total correctness of programs dealing with infinite structures one must guarant...
Abstract. We introduce an extension of Hoare logic for call-by-value higherorder functions with ML-like local reference generation. Local references may be generated dynamically an...
Bounded treewidth and Monadic Second Order (MSO) logic have proved to be key concepts in establishing fixed-parameter tractability results. Indeed, by Courcelle's Theorem we ...
