Theoretical Aspects of Computer Software International Conference TACS ’91, Sendai, Japan, September 24–27, 1991. Proceedings

TACS'91 is the first International Conference on Theoretical Aspects of Computer Science held at Tohoku University, Japan, in September 1991. This volume contains 37 papers and an abstract for the talks presented at the conference. TACS'91 focused on theoretical foundations of programming, and theoretical aspects of the design, analysis and implementation of programming languages and systems. The following range of topics is covered: logic, proof, specification and semantics of programs and languages; theories and models of concurrent, parallel and distributed computation; constructive logic, category theory, and type theory in computer science; theory-based systems for specifying, synthesizing, transforming, testing, and verifying software.

A semantics for type checking.- Type inference in polymorphic type discipline.- Monotone recursive definition of predicates and its realizability interpretation.- Adding proof objects and inductive definition mechanisms to frege structures.- From term models to domains.- An abstract interpretation for ML equality kinds.- Full abstraction and the Context Lemma (preliminary report).- An efficiency preorder for processes.- On nets, algebras and modularity.- Towards a complete hierarchy of compositional dataflow models.- Type theory as a foundation for computer science.- What is in a step: On the semantics of statecharts.- Proving termination of general Prolog programs.- On abstraction and the expressive power of programming languages.- Role of logic programming in the FGCS project.- Authentication and delegation with smart-cards.- Data flow analysis as model checking.- On the adequacy of dependence-based representations for programs with heaps.- From programming-by-example to proving-by-example.- From LP to LP: Programming with constraints.- Polynomial recursion analysis in pascal like programs.- Complexity of proving program correctness.- Some normalization properties of martin-löf's type theory, and applications.- Parametricity of extensionally collapsed term models of polymorphism and their categorical properties.- Programs with continuations and linear logic.- ?-Calculus semantics of object-oriented programming languages.- Wrapper semantics of an object-oriented programming language with state.- Sharing actions and attributes in modal action logic.- First order data types and first order logic.- Efficient program synthesis: Semantics, logic, complexity.- Principal type-schemes of BCI-lambda-terms.- Intersection and union types.- The coherence of languages withintersection types.- Singleton, union and intersection types for program extraction.- Subtyping + extensionality: Confluence of ??top reduction in F?.- An extension of system F with subtyping.- Will logicians be replaced by machines?.
