We present a variant of the linear logical framework LLF that avoids the restriction l-typed terms be in pre-canonical form and adds -abstraction at the level of families. We aban...
Operational semantics provide a simple, high-level and elegant means of specifying interpreters for programming languages. In natural semantics, a form of operational semantics, p...
We report on work in progress devoted to the formalization of an Ordered Logical Framework (OLF) based on a two-level architecture [8] in the Hybrid system. OLF here is a second-or...
We present an authorization logic that permits reasoning with explicit time. Following a proof-theoretic approach, we study the meta-theory of the logic, including cut elimination...
Abstract. Twelf is a meta-logical framework for the specification, implementation, and meta-theory of deductive systems from the theory of programming languages and logics. It rel...
