  Mass angular momentum and charge inequalities for axisymmetric maximal
time-symmetric initial data invariant under an action of U(1) group, in
Einstein-Maxwell-axion-dilaton gravity being the low-energy limit of the
heterotic string theory, is established. We assume that data set with two
asymptotically flat regions is given on smooth simply connected manifold. We
also pay attention to the area momentum charge inequalities for a closed
orintabler two-dimensional spacelike surface embedded in the spacetime of the
considered theory.
