Jos Vermaseren (Amsterdam):
Some algebraic methods in Field Theory
Abstract:
The methods for computing Feynman diagrams
have become more and more sophisticated over the years. Lately much progress has been
made to express them in terms of Harmonic Sums. In this talk I will show some techniques
by which these sums can be manipulated. This is applied to two interesting problems:
one is how to express Multiple Zeta Values into a minimal set and the other concerns
the solving difference equations. These problems will be placed in their physics context.
