Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.
I split some material specific to Kashiwara-Vergne conjecture from Hausdorff series and added more references and a quoted idea from a seminar page. Related to Drinfeld associator (with which it has a serious overlap, especially in references) and few related pages I work on these days.
A student asked “What is a cobordism?” and I checked and realized that the Lab entry cobordism was effectively empty.
So I have now added some basic text in the Idea-section and added a bare minimum of references. Much more should be done of course, but at least now there are pointers.
need a place to record the references on heterotic NS5-branes as “small Yang-Mills instantons”:
Andrew Strominger, Heterotic solitons, Nucl.Phys. B343 (1990) 167-184 (doi:10.1016/0550-3213(90)90599-9) Erratum: Nucl.Phys. B353 (1991) 565-565 (doi:10.1016/0550-3213(91)90349-3) (spire:)
Edward Witten, Small Instantons in String Theory, Nucl.Phys.B460:541-559, 1996 (doi:10.1016/0550-3213(95)00625-7)
So I am finally starting this entry here

added pointer to the Encyclopedia.com entry which turns out to have more detailed scientific information than Wikipedia
(happened to need to look up which work of Gauss came out of his occupation with geodesy; and Wikipedia is most brief about this, while Encyclopedia.com has thorough three paragraphs on it)
will also cross-link our Gaussian entries with this one now…
stub entry, to go with the list of Sullivan models – examples. But for the moment it’s nothing but a place to record this reference:
only now do I realize that we have parallel entries
I suppose these refer to the same person and should be merged?
Even after some googling I can only find this very likely.
merged entry with duplicate Stephen Halperin
added pointer to discussion of bar-cobar construction for dg-Hopf algbebras

I started comma double category. Since I care about equipments more than double categories in general, and because it actually is an instance of a comma object, I made the article mostly about virtual double categories. I wrote down a couple of conjectures about when the comma has units and composites, but haven’t verified them yet and not sure when I will.
After this discussion at string diagrams for linearly distributive categories with unit = counit, I finally got round to having a go at making star-polycategory. Still much more to do. Hopefully I didn’t make any major mistakes so far.

I do think the phrasing “dense set (i.e. a countable intersection of dense opens)” was a bit confusing, since “i.e.” means “in other words”, but here it applies only to the immediately preceding words “ set” rather than the entire phrase “dense set”. So I changed it to “dense set (i.e. a countable intersection of dense opens that is itself dense)”.
