Comments on "Inverse scattering method and soliton solution family for the Einstein–Maxwell theory with multiple Abelian gauge fields"

This paper points out that equations (18a) and (18b) in Ref. 7 Gao Y J 2008 Chin. Phys. B 17 3574 only possess the solutions M=\pm \rho\tilde\gamma\varepsilon. So, there does not exist the so-called soliton solution family for the Einstein–Maxwell theory with multiple Abelian gauge fields shown in Ref. 7.
