Galois coverings of categories
A covering of a category is defined much like a covering of a topological space. Coverings of small categories can be classified using a categorical analogue to the ``fundamental groupoid''. Focusing on the subclass of ``Galois'' (or ``Regular'') coverings, we give a (reasonably) concrete description of Galois coverings, and construct the universal Galois cover of a small category.
