High Quality Content by WIKIPEDIA articles! In mathematics, the simplicial category (or ordinal category) is a construction in category theory used to define simplicial and cosimplicial objects.The simplicial category is usually denoted by ? and is sometimes denoted by Ord. There are several equivalent descriptions of this category. ? can be described as the category of finite ordinals as objects, thought of as totally ordered sets, and order preserving functions as morphisms. The category is generated by coface and codegeneracy maps, which amount to inserting or deleting elements of the orderings. (See simplicial set for relations of these maps.)
