A Bidirectional Refinement Type System for LF
We present a system of refinement types for LF in the style of recent formulations where only canonical forms are well-typed. Both the usual LF rules and the rules for type refine...

A Refinement Calculus for the Development of Real-Time Systems
We present a calculus which can transfer specifications to objects for the development of real-time systems. The object model is based on a practical OO development technique--HRT...

Modular refinement in novel schema calculi
Using the language Z for more than specification is hindered by the fact that its algebra of schemas is not monotonic with respect to refinement; so specification is modular, but ...

On the Relative Complexity of Resolution Refinements and Cutting Planes Proof Systems
An exponential lower bound for the size of tree-like cutting planes refutations of a certain family of conjunctive normal form (CNF) formulas with polynomial size resolution refuta...
