Generation of asymptotically flat soliton solutions with current algebra limit in Einstein-Maxwell-dilaton theory

A new 2N-soliton solution is constructed for the electric/magnetic sector of the four-dimensional dilaton-Maxwell gravity with arbitrary value of coupling in the static and axisymmetric case. This solution possesses an infinitesimal limit of the current algebra form and preserves the asymptotic flatness property being applied to the asymptotically flat background.
