Kramer--Neugebauer Transformation for Einstein--Maxwell--Dilaton--Axion Theory
Abstract
The Kramer--Neugebauer--like transformation is constructed for the stationary axisymmetric D=4 Einstein--Maxwell--dilaton--axion system. This transformation directly maps the dualized sigma--model equations of the theory into the nondualized ones. Also the new chiral 4 × 4 matrix representation of the problem is presented.
