On (Un)Soundness of Unravelings
We revisit (un)soundness of transformations of conditional into unconditional rewrite systems. The focus here is on so-called unravelings, the most simple and natural kind of such ...

Simulation in the Call-by-Need Lambda-Calculus with letrec
This paper shows the equivalence of applicative similarity and contextual approximation, and hence also of bisimilarity and contextual equivalence, in the deterministic call-by-nee...

Proving Productivity in Infinite Data Structures
For a general class of infinite data structures including streams, binary trees, and the combination of finite and infinite lists, we investigate a notion of productivity. This ...

Order-Sorted Unification with Regular Expression Sorts
Abstract. We extend first-order order-sorted unification by permitting regular expression sorts for variables and in the domains of function symbols. The set of basic sorts is ...

Higher-Order (Non-)Modularity
We show that, contrary to the situation in first-order term rewriting, almost none of the usual properties of rewriting are modular for higher-order rewriting, irrespective of the...
