are in
hep-ph,
hep-th,
q-alg,
or in gr-qc,
and include my Habilschrift: Renormalization and Knot Theory
(q-alg/9607022) ,
and further recent results on Knots, transcendental Numbers and
Feynman diagrams,
as well as work on two-loop integral representations for massive
2-,3-, and 4-point. A total summary including some older papers
you can access via spires here.
Recently, I got interested in a connection between Hopf
algebras and renormalization (q-alg/9707029).
There is an intriguing connection to Noncommutative Geometry,
which was explored in a collaboration with Alain Connes. You can
download the initial paper here.
Most recently, Alain and I discovered a connection between renormalization and the Riemann--Hilbert problem, which lead to the RHI and RHII papers. A review of all these developments is hep-th/0010059.
I am still investigating the 4-term relation.
This puts overall counterterms of Feynman diagrams in the context
of weight systems. These, in turn, are related to Vassiliev
invariants, as shown by Dror Bar-Natan.
You will find here bibliographical
notes
on older papers concerning Knot/Number/Field Theory
by Broadhurst, myself, and coworkers.
