stub for jet bundle

]]>added more “selected writings”, more hyperlinks to keywords; gave the references temporal ordering, and disentangled publications from other links and pointers

]]>added this pointer:

- Damien Calaque, Pavel Etingof,
*Lectures on tensor categories*, IRMA Lectures in Mathematics and Theoretical Physics 12, 1-38 (2008) (arXiv:math/0401246)

Add a reference for string diagrams in closed monoidal categories

]]>starting some minimum

]]>starting a small entry here, for ease of hyperlinking. This is to go along with *metric Lie algebra*

am splitting this off from n-Lie algebra (which should better be renamed to Filippov algebra)

– am being interrupted now – not done yet…

]]>Added link to group extension entry at https://ncatlab.org/nlab/show/group+extension

]]>brief `category:people`

-entry for hyperlinking (at *Faulkner construction*, presently redirecting to *M2-brane 3-algebra*) this reference:

- John Faulkner,
*On the geometry of inner ideals*, Journal of Algebra Volume 26, Issue 1, July 1973, Pages 1-9 (doi:10.1016/0021-8693(73)90032-X)

(I hope I have identified the author’s webpage correctly – if anyone knows, please check)

]]>added some actual text to the category:people entry *Roger Penrose*

I incorporated some of my spiel from the blog into the page [[type theory]].

]]>I was looking for a place to record a somewhat more global overview of the notion of *locally presentable category*, its related notions and its generalizations to higher category theory. But somehow all of the existing entries feel too narrow in focus to accomodate this. So I ended up creating now a new entry titled

Think of this as accomodating material such as one might present in a seminar talk that is meant to bring people with some basic background up to speed with the relevant notions, without going into the wealth of technical lemmas.

I only just started. Will continue in a moment after a short break…

]]>Started writing down the definition.

-entry for hyperlinking references at *M2-brane 3-algebra*

Another reference added.

]]>I’ve removed this query box from metric space and incorporated its information into the text:

]]>Mike: Perhaps it would be more accurate to say that the symmetry axiom gives us enriched $\dagger$-categories?

Toby: Yeah, that could work. I was thinking of arguing that it makes sense to enrich groupoids in any monoidal poset, cartesian or otherwise, since we can write down the operations and all equations are trivial in a poset. But maybe it makes more sense to call those enriched $\dagger$-categories.

New stub for the notion of clone in universal algebra, including a reference relating it to operads.
