* 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.

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

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

  - Implementation: graphs, nets, abstract machines, explicit
    substitution, rewriting tools, compilation techniques.

  - Semantics: operational semantics, denotational semantics,
    separability, higher-order abstract syntax.

** Special session in honour of Kris Rose
----------------------------------------------------------------------

Kristopher H. (Kris) Rose has been an active member of the HOR
community.  He contributed to almost all the editions of HOR and he
served as PC chair of the 7th edition (Vienna 2014).

The next one will be the first edition without Kris, and a special
session will be dedicated to honour him: to thank him for his
continuous support to HOR and to acknowledge his key role in the
development of explicit substitutions.

If you would like to give a short address in his memory or your
submission his related to Kris work, please contact the PC chair
      Stefano Guerrini  (mailto:stefano.guerrini at univ-paris13.fr)

** Submission Guidelines
----------------------------------------------------------------------

To give a presentation at the workshop, submit an extended abstract
(between 2 to 5 pages} via Easychair

      https://easychair.org/conferences/?conf=hor18

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.

The workshop has informal, electronic proceedings that will be
included in the FLoC 2018 electronic proceedings.

Submission is via Easychair at
