* OVERVIEW

HOR is a forum to present work concerning all aspects of higher-order rewriting.

HOR aims to provide an informal and friendly setting to discuss recent work and work in progress concerning higher-order rewriting, broadly construed. This includes rewriting systems that have functional variables or bound variables, the lambda-calculus and combinatory logic being paradigmatic examples.

* TOPICS

The following is a non-exhaustive list of topics for the workshop:

- Applications: proof checking, theorem proving, generic programming, declarative programming, program transformation, automated termination/confluence/equivalence analysis tools.

- Foundations: pattern matching, unification, strategies, narrowing, termination, syntactic properties, type theory, complexity of derivations.

- Frameworks: term rewriting, conditional rewriting, graph rewriting, net rewriting, comparisons of different frameworks.

- Implementation: explicit substitution, rewriting tools, compilation techniques.

- Semantics: semantics of higher-order rewriting, categorical rewriting, higher-order abstract syntax, games and rewriting.

HOR is a platform for discussing open questions, ongoing research, and new perspectives, as well as new results. Extended abstracts describing work in progress, preliminary results, research projects, or problems in higher-order rewriting are very welcome. Specifically, short versions of recently published papers are welcome, and submission to HOR does not preclude formal publication at other venues.

The workshop has informal electronic proceedings that will be made available on the workshop website.
