The invariant charges of the Nambu-Goto-String
- Dorothea Bahns (Universität Hamburg, Hamburg, Germany)
Abstract
A string in a flat background is an integrable system allowing for the construction of an algebra of diffeomorphism-invariant functionals on the worldsheet. The approach where this algebra is used as a starting point for quantization is reviewed and it is shown that it is inequivalent to quantization methods based on Fock space -- even in the critical dimension and regardless of the ordering prescription.
