A friend just emailed me the following guestion, would anyone know what this field is called please.(adsbygoogle = window.adsbygoogle || []).push({});

"A few years ago a friend and colleague of mine had told me about a branch of mathematics or metamathematics that dealt with mapping entire sub-disciplines of mathematics and, I think, physics.

This had seemed to me or perhaps he told me that this was an extension of topology, and I distinctly remember getting a text on the subject and starting, though only starting to read it.

The question is: what is the name of this subject. It's not category theory nor is it fuzzy set theory, though that's been ""'s primary focus for some time. I thought it was something relatively short beginning with a 'T'.

I've had no luck trying to find the term on the WEB."

Thank you,

Suzanne
