Higher-Dimensional Rewriting and Applications
(HDRA 2016)

Deadline for submitting contributions to the HDRA workshop has been extended to

        *** 27th of April, 2016 ***


Second edition of the workshop on Higher-Dimensional Rewriting and Applications
25-26 June 2016, Porto, Portugal
Co-located with the FSCD conference


Over recent years, rewriting methods have been generalized from strings and
terms to richer algebraic structures such as operads, monoidal categories, and
more generally higher-dimensional categories. These extensions of rewriting fit
in the general scope of higher-dimensional rewriting theory, which has emerged
as a unifying algebraic framework. This approach allows one to perform
homotopical and homological analysis of rewriting systems (Squier theory). It
also provides new computational methods in the study of coherence of
higher-dimensional algebraic structures, in combinatorial algebra (Artin-Tits
monoids, Coxeter and Garside structures), in homotopical and homological algebra
(construction of cofibrant replacements, Koszulness property). The workshop is
open to all topics concerning higher-dimensional generalizations and
applications of rewriting theory, including

- higher-dimensional rewriting: polygraphs / computads, higher-dimensional
  generalizations of string/term/graph rewriting systems, etc.

- homotopical invariants of rewriting systems: homotopical and homological
  finiteness properties, Squier theory, algebraic Morse theory, coherence
  results in algebra and higher-dimensional category theory, etc.

- linear rewriting: presentations and resolutions of algebras and operads,
  Gröbner bases and generalizations, homotopy and homology of algebras and
  operads, Koszul duality theory, etc.

- applications of higher-dimensional and linear rewriting and their interactions
  with other fields: calculi for quantum computations, algebraic lambda-calculi,
  proof nets, topological models for concurrency, homotopy type theory,
  combinatorial group theory, etc.

- implementations: the workshop will also be interested in implementation issues
  in higher-dimensional rewriting and will allow demonstrations of prototypes of
  existing and new tools in higher-dimensional rewriting.
