摘要: 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 Mργε. 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].

关键词: matrix potential, extended hyperbolic complex, soliton solution

Abstract: 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].

Key words: matrix potential, extended hyperbolic complex, soliton solution
