Matrix Ernst Potentials and Orthogonal Symmetry for Heterotic String in Three Dimensions
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.Comment: 10 pages in LaTe
Charging Symmetries and Linearizing Potentials for Einstein-Maxwell Dilaton-Axion Theory
We derive a set of complex potentials which linearize the action of charging
symmetries of the stationary Einstein-Maxwell dilaton-axion theory.Comment: 10 pages in LaTe
