Uncovering the detailed structure of the algebra formed by the invariant charges of closed bosonic strings moving in 1+2-dimensional Minkowski space

Abstract

For the Nambu-Goto theory of closed, bosonic strings moving in three space-time dimensions, generating relations of degree ≤6 for the Poisson algebra of the infinitesimal generators of observable symmetry transformations have been computed. These computations result in a deeper insight into the structure of the symmetry algebra. In addition, a parametrization of the quantum corrections for the generating relations of degree 3 is given.
