    • I decided that nLab is probably a better place to develop my ideas than ‘wikipedia’, where I posted one article on this topic but never felt confident to add more, since wikipedia is not really meant for ’ongoing research’. I really liked the idea of using this space for ’public notes on my research’ and am looking forward to getting reactions from some of you.

      As a starter, I feel that using the first-person form in my reporting is more ’honest’ regarding the academic status of the piece. Prefix orders are not an accepted notion in literature yet, I think. The notion itself is used often, but always in a specific context and was (as far as I know) never generalized - until now…

    • When writing my page on prefix orders, I found the need to refer to the page on trees. As it turns out, the order theoretic definition that I know for trees was not on it yet, so I decided to add it.

    • cross-linked with all nnLab pages that cite Lyubashenko

      diff, v3, current

    • Added a description of slant products in cohomology. Added references to Dold’s book.

      diff, v5, current

    • Update diagrams to tikzcd syntax. Also removed comment about using “Leibniz order” for composition of morphisms, which IMHO was unnecessary and confusing.

      diff, v9, current

    • A stub here. Is there a ready example?

      v1, current

    • suddenly I found a bunch of further references on this, so I am giving this its own entry now, for ease of recording stuff

    • am giving this elementary-but-important fact its own entry, for ease of referencing

      v1, current

    • Created page to record some definitions. I am unable to see the relationship between Bousfield’s definition and Joyal’s, although I included some partial results.

      v1, current

    • created a page for Peter Symonds (Manchester)

      v1, current

    • I want to make a list with (historical) null results in experimental physics that have been important for development of theoretical physics. Puny start so far, hope to collect more

    • slightly expanded the text, realizing more cross-links to existing entries (such as black body radiation). But this and related entries still remain stubs.

      same comment applies as I just made at chemical element:

      added pointer to

      For a while I thought that this proposal is completely crazy. But in view of the established success of Skyrmion models for atomic nuclei and in particular with these viewed within the Sakai-Sugimoto model, it doesn’t seem completely crazy anymore. I still think it must be admitted that the concrete evidence that there is an actual model of nuclie by complex surfaces is extremely weak and very vague, but I can see now why it is interesting and maybe even tantalizing.

      v1, current

    • changed page name to singluar

      added mentioning of atomic number

      added pointer to

    • started something at quiver gauge theory; some very basic sentences on the Idea of it all, and some bare minimum of references.

      This is a vast subject, and clearly that entry deserves to be expanded much further.

      In the course of creating this I needed to create brief entries B-brane and exceptional collection.

    • The example of QQ as a Bishop set on the preset Z×ZZ \times Z is wrong. You need to rule out zero denominators. The definition currently on the page is not a Bishop set at all, because 0/00/0 makes the relation intransitive.

      I’m not sure how it should be changed to illustrate the point that the same preset can get distinct sets. Maybe a different example entirely?

      diff, v17, current

    • Created page to record this construction, which I just rediscovered, and its relationship to semi-left-exact reflections in 1-category theory.
