Conditional Automata: A Tool for Safe Removal of Negligible Events
Abstract. Polynomially accurate simulations [19] are relations for Probabilistic Automata that require transitions to be matched up to negligible sets provided that computation len...

Complete Lax Logical Relations for Cryptographic Lambda-Calculi
Abstract. Security properties are profitably expressed using notions of contextual equivalence, and logical relations are a powerful proof technique to establish contextual equiva...

On Completeness of Logical Relations for Monadic Types
Interesting properties of programs can be expressed using contextual equivalence. The latter is difficult to prove directly, hence (pre-)logical relations are often used as a tool ...

Relational Parametricity for Computational Effects
According to Strachey, a polymorphic program is parametric if it applies a uniform algorithm independently of the type instantiations at which it is applied. The notion of relatio...

Finding Relations Among Linear Constraints
In program analysis and verification, there are some constraints that have to be processed repeatedly. A possible way to speed up the processing is to find some relations among the...
