%0 Journal Article %T Enlargements of Categories %A Lars Bruenjes %A Christian Serpe %J Mathematics %D 2004 %I arXiv %X In order to apply nonstandard methods to modern algebraic geometry, as a first step in this paper we study the applications of nonstandard constructions to category theory. It turns out that many categorial properties are well behaved under enlargements. %U http://arxiv.org/abs/math/0408177v1
