Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.

• I have added some stuff about the consturction and the (fatal) non-functoriality of Moore spaces to Moore space. I know the page doesn’t look so good and the proof is somewhat sloppy, but I would still be happy if someone would take a look.

• some minimum, to have a place to record references

• starting some minimum here , for the moment I just need a place to record references on dyonic membranes…

• Created Sasakian manifold. This seems vaguely related to conifold/$G_2$-manifold stuff, but the state of the art in the Sasakian world seems very much experimental: difficult to find any large families of such structures.

• page for Rudolf Fritsch. Just link to wikipedia entry at present.

• I have added at HomePage in the section Discussion a new sentence with a new link:

If you do contribute to the nLab, you are strongly encouraged to similarly drop a short note there about what you have done – or maybe just about what you plan to do or even what you would like others to do. See Welcome to the nForum (nlabmeta) for more information.

I had completly forgotton about that page Welcome to the nForum (nlabmeta). I re-doscivered it only after my recent related comment here.

• Added some more general references to work on topological joins.

• Page created, but author did not leave any comments.

• I worked on brushing up (infinity,1)-category a little

• mostly I added in a section on homotopical categories, using some paragraphs from Andre Joyal's message to the CatTheory mailing list.

• in this context I also rearranged the order of the subsections

• I removed in the introduction the link to the page "Why (oo,1)-categories" and instead expanded the Idea section a bit.

• added a paragraph to the beginning of the subsection on model categories

• added the new Dugger/Spivak references on the relation between quasi-cats and SSet-cats (added that also to quasi-category and to relation between quasi-categories and simplicial categories)

• added references and various quick remarks, such as that the subspace of Cayley 4-planes

$CAY \subset Gr(4,8)$

has this coset space structure:

$CAY \;\simeq\; Spin(7)/\big( Spin(4).Spin(3)\big)$

I am guessing we also have

$\cdots \simeq Spin(8)/\big( Spin(5).Spin(3)\big)$

(??)

• starting something, but nothing here yet

• Page created, but author did not leave any comments.

• Gave new definition of kilogram, and rephrased reference to old definition in terms of the Grand K.

• Page created, but author did not leave any comments.

• started some remarks at physical unit. But I really need to stop with that now and do more urgent things…

• Page created, but author did not leave any comments.

• removed broken link, changed page name to exactly what Maths Genealogy has

• Page created, but author did not leave any comments.

• brief category:people-entry for hyperlinking references at Sp(n).Sp(1)

• Page created, but author did not leave any comments.
