Dual enrichment and Isbell Duality
 
 
Description:  The category of presheaves on a given small category is enriched in the category of presheaves on its opposite. This piece of Category Theory folklore is under appreciated perhaps because it is not clear what to do with it. I shall discuss versions of this phenomenon and how it looks from the perspective of Isbell duality. Than I shall outline some possible applications of the ideas.
