Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.
added to Yang-Mills instanton a discussion of instantons as tunnelings between Chern-Simons vacua.
added an Idea-paragraph to non-perturbative effect, also to perturbation theory - divergence/convergence.
brief category:people-entry for hyperlinking references at fiber bundles in physics and mathematical physics
Started an entry in “category:motivation” on fiber bundles in physics.
(prompted by this Physics.SE question)
I have added to string theory a new section Critical strings and quantum anomalies.
Really I was beginning to work on a new entry twisted spin^c structure (not done yet) and then I found that a summary discussion along the above lines had been missing.
added pointer to:
<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>
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.
stub for Hořava-Witten theory
wrote parallel transport (which was previously redirecting to connection on a bundle).
Also rewrote Dyson formula.
I have touched the Examples-section at sequentially compact topological space:
moved the detailed discussion of the compact space which is not sequ compact to the examples-section at compact topological space, and left a pointer to it,
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 a reference to
Created the page atomic topos and moved some of the material from atomic geometric morphism over.
started M-theory on G2-manifolds
added some comments on history to neutrino.
added to renormalization group the explanation of how the Stückelberg-Petermann renormalization group relates to the Gell-Mann-Low renormalization cocycle (in general not a group).
For the moment and for completeness, I copied the same text into these three entries. All these entries are still stubs. They will pick up more distinct content in a while..
