Abstract
The Sp (4, R)/ GL (2, R) matrix operator defining the family of isotropic geodesic lines in the target space of the stationary D = 4 Einstein–Maxwell–dilaton–axion theory is constructed. This operator is used to derive a class of solutions describing a system of point centers with nontrivial values of mass, parameter NUT, as well as electric, magnetic, dilaton and axion charges. It is shown that this class contains the Majumdar–Papapetrou-like solutions and also the solutions for massless naked singularities.Keywords
