Center node: "towards 3 dimensional rewriting theory"
  Abstract: String rewriting systems have proved very useful to study monoids. In good#R##N#cases, they give finite presentations of monoids, allowing computations on those and#R##N#their manipulation by a computer. Even better, when the presentation is confluent and#R##N#terminating, they provide one with a notion of canonical representative of the elements of#R##N#the presented monoid. Polygraphs are a higher-dimensional generalization of this notion of#R##N#presentation, from the setting of monoids to the much more general setting of n-categories.#R##N#One of the main purposes of this article is to give a progressive introduction to the notion#R##N#of $\higher-dimensional\ rewriting\ system$provided by polygraphs, and describe its links with#R##N#classical rewriting theory, string and term rewriting systems in particular. After introducing#R##N#the general setting, we will be interested in proving local confluence for polygraphs presenting#R##N#2-categories and introduce a framework in which a finite 3-dimensional rewriting system#R##N#admits a finite number of critical pairs
