M ay 2 00 8 Invariants from classical field theory
نویسنده
چکیده
We introduce a method that generates invariant functions from perturbative classical field theories depending on external parameters. Applying our methods to several field theories such as abelian BF , Chern-Simons and 2-dimensional Yang-Mills theory, we obtain, respectively, the linking number for embedded submanifolds in compact varieties, the Gauss’ and the second Milnor’s invariant for links in S, and invariants under area-preserving diffeomorphisms for configurations of immersed planar curves.

We argue that the quantized non-Abelian gauge theory can be obtained as the infrared limit of the corresponding classical gauge theory in a higher dimension. We show how the transformation from classical to quantum field theory emerges, and calculate Planck's constant from quantities defined in the underlying classical gauge theory.

We propose a generalization of Gysin maps for DM-type morphisms of stacks F → G that admit a perfect relative obstruction theory E F/G. We prove functoriality properties of the generalized Gysin maps. As applications, we analyze Gromov-Witten invariants of blow-ups and we give a short proof of Costello’s push-forward formula.

With the help of the complex structure and the wave operator of the nonlinear classical Klein-Gordon equation with the interaction u4 we define the Wick kernel of the interacting quantum field in four-dimensional space-time and consider its properties. In particular, the diagonal of this Wick kernel is (real) solutions of the classical nonlinear Klein-Gordon equation with the interaction u4.

This is a introductory survey of some recent developments of “Galois ideas” in Arithmetic, Complex Analysis, Transcendental Number Theory and Quantum Field Theory, and of some of their interrelations.
