   I’m trying to create a new page ’nucleus of a profunctor’ but getting an error message

   Internal Error

   An application error occurred while processing your request.

   But I was able to make a change to an existing page. Are others seeing this?

   Format: MarkdownItexIt seems to be working now, I was able to create [[nucleus of a profunctor]]. I have reported the bug fix to Jacques.

   Format: MarkdownItexGreat! I started an entry there. Much more could be said, including plenty of examples. I don't know what people think about splitting examples into those where the profunctor is Hom from the rest. Do we not already have something on the 'center of an adjunction', perhaps under a different name? We have [[Legendre transfomation]]. Is there a standard way to take the Legendre-Fenchel transform as a generalization?
