A Note on "M - component nonlinear evolution equations: multiple soliton solutions"
We analyze the recent paper by Wazwaz [Wazwaz A.M., M - component nonlinear evolution equations: multiple soliton solutions, Phys. Scr. 81 (2010) 055004]. We demonstrate that author did not consider in essence the M - component nonlinear evolution equations but he reduced the M - component equations to the well - known Korteweg - de Vries equation, to modified Korteweg - de Vries equation and to the Kadomtsev - Petviashvili equation. To find multiple soliton solutions for these well - known equations author has used the Hirota method.
