Noncommutative field theory - quasiplanar Wick products
- Dorothea Bahns (Albert-Einstein-Institut, MPI für Gravitationsphysik)
Abstract
A generalization of the concept of a local counterterm suitable for field theories on noncommutative spacetimes leads to a modified definition of well-defined products of fields, called quasiplanar Wick products. The drastic physical consequences of this definition are mentioned.
