Note:These pages make extensive use of the latest XHTML and CSS Standards. They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

Abstract:
Posted at February 17, 2006 3:18 PM UTC-transports are an -functors describing
parallel trasport in -bundles
propagation in -dimensional QFT.We describe basic notions of -transport theory, such as trivialization, transition and trace and discuss examples.
This is a synthesis of the material contained in [I, II, III, IV, V, VI].

This looks fascinating. Wish I could be there to hear it. Good luck!

PS: How far away are you from describing string theory within this framework of transport, i.e. QFT, on loop space (if that was the goal)? :)

I am trying to show that certain “2-vector” transport (transport with target the 2-category of module categories over an abelian monoidal category ) captures topological strings as described by Fukuma-Hosono-Kawai and captures CFT as described by Fuchs-Runkel-Schweigert. This does seem to work, at least concerning some aspects of these formulations.
As I have tried to point out recently, such 2-vector transport can be understood as sort of a categorified QM. In particular, if you restrict attention to the vertical composition of 2-morphisms you do get something like QM on path space from this.
So, I think, yes, this does work. There are however many loose ends that need to be worked out further.
