A lattice Poisson algebra for the Pohlmeyer reduction of the AdS_5 x S^5 superstring

arXiv:1204.2531 · doi:10.1016/j.physletb.2012.06.028

Abstract

The Poisson algebra of the Lax matrix associated with the Pohlmeyer reduction of the AdS_5 x S^5 superstring is computed from first principles. The resulting non-ultralocality is mild, which enables to write down a corresponding lattice Poisson algebra.
