Matrix Ernst potentials for EinsteinMaxwelldilatonaxion with multiple vector fields
Abstract
We show that the EinsteinMaxwelldilatonaxion system with multiple vector fields (bosonic sector of the D = 4, N = 4 supergravity) restricted to spacetimes possessing a nonnull Killing vector field admits a concise representation in terms of the Ernsttype matrix valued potentials. A constructive derivation of the SWIP solutions is given and a colliding waves counterpart of the DARNNUT solution is obtained. SU (m, m) chiral representation of the twodimensionally reduced system is derived and the corresponding KramerNeugebauertype map is presented.
