Nearly locally presentable categories

L. Positselski and J. Rosicky

We introduce a new class of categories generalizing locally presentable ones. The distinction does not manifest in the abelian case and, assuming Vopenka's principle, the same happens in the regular case. The category of complete partial orders is the natural example of a nearly locally finitely presentable category which is not locally presentable.

Keywords: locally presentable categories, special directed colimits, nearly presentable objects, regular factorizations, abelian categories, complete partial orders
