Matrix Ernst Potentials and Orthogonal Symmetry for Heterotic String in Three Dimensions
Alfredo Herrera-Aguilar, Oleg Kechkin
Abstract
A new matrix representation for low-energy limit of heterotic string theory reduced to three dimensions is considered. The pair of matrix Ernst Potentials uniquely connected with the coset matrix is derived. The action of the symmetry group on the Ernst potentials is established.
