Abstract:
I will describe a project to develop a vast
expanse of constructible quantum field
theories of extended objects in 2n-
dimensional space-time manifolds. For
every 2d qft, there is to be a qft of
extended objects in every 2n-dimensional
space-time. These are to be constructible
in the same senses that 2d qfts are
constructible. The quantum fields live on
"quasi Riemann surfaces" --- certain
spaces of integral (n-1)-currents in the
space-time manifold, which are complete
metric spaces with much the same
analytic properties as Riemann surfaces.
(The notion of integral current is borrowed
from Geometric Measure Theory.)
