    • added to Yang-Mills instanton a discussion of instantons as tunnelings between Chern-Simons vacua.

    • This comment is invalid XML; displaying source. <p>I added three more references to <a href="http://ncatlab.org/nlab/show/Bredon+cohomology">Bredon cohomology</a>.</p> <p>two of them, by H. Honkasolo, discuss a sheaf-cohomology version of Bredon cohomology, realized as the cohomology of a topos built from the <a href="http://ncatlab.org/nlab/show/orbit+category">orbit category</a>.</p> <p>It's too late for me today now to follow this up in detail, but I thought this might be of interest in the light of our discussion at <a href="http://www.math.ntnu.no/~stacey/Vanilla/nForum/comments.php?DiscussionID=650&page=1">G-equivariant stable homotopy theory</a>.</p>
    • Hello, I thought that a new entry would be a good thing. Just a sketch for now.

    • am starting something, not done yet, nothing to be seen here for the moment…

    • apparently this was a typo for and duplicate of Augusto Sagnotti – am clearing the entry (a stub anyway), adding redirect to the proper entry

    • started adding rules to sequent calculus, but have to interrup now and hunt some food

    • Brief idea of the E-string, pointer to and snippet from one reference that makes it nicely explicit.

      I am compiling this and related entries because we have a clean mathematical formalization of this zoo of structures now in terms of equivariant super homotopy theory (as surveyed here). Once everything is cleaned up and published, I will try to go through all the entries and accompany the vague Idea-sections with some solid mathematics.

    • I have touched the Examples-section at sequentially compact topological space:

      1. moved the detailed discussion of the compact space {0,1} [0,1]\{0,1\}^{[0,1]} which is not sequ compact to the examples-section at compact topological space, and left a pointer to it,

      2. added pointers (just pointers for the moment) to two detailed discussions of examples of sequ compact spaces that are not compact.

    • Jim Stasheff pointed out a reference that discusses categorifications of associahedra. I added the ref to associahedron

    • added some comments on history to neutrino.
