Termination checking with types

Andreas Abel (2004)

RAIRO - Theoretical Informatics and Applications - Informatique Théorique et Applications

The paradigm of type-based termination is explored for functional programming with recursive data types. The article introduces Λ μ + , a lambda-calculus with recursion, inductive types, subtyping and bounded quantification. Decorated type variables representing approximations of inductive types are used to track the size of function arguments and return values. The system is shown to be type safe and strongly normalizing. The main novelty is a bidirectional type checking algorithm whose soundness is...

Thread algebra for noninterference

Thuy Duong Vu (2009)

RAIRO - Theoretical Informatics and Applications - Informatique Théorique et Applications

Thread algebra is a semantics for recent object-oriented programming languages [J.A. Bergstra and M.E. Loots, J. Logic Algebr. Program. 51 (2002) 125–156; J.A. Bergstra and C.A. Middelburg, Formal Aspects Comput. (2007)] such as C# and Java. This paper shows that thread algebra provides a process-algebraic framework for reasoning about and classifying various standard notions of noninterference, an important property in secure information flow. We will take the noninterference property given by...
