About: Polygraph (mathematics)

An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In mathematics, and particularly in category theory, a polygraph is a generalisation of a directed graph. It is also known as a computad. They were introduced as "polygraphs" by and as "computads" by Ross Street. In the same way that a directed multigraph can freely generate a category, an n-computad is the "most general" structure which can generate a free n-category.
