• Nonlinear Alfven wave propagating parallel to a constant magnetic field in an ultra-relativistic electron-positron plasma is investigated in a frame of covariant two-fluid model equation. It is shown that the nonlinear evolution of circular polarized Alfven wave is described by (∂B)/(∂τ)+a (∂^3B)/(∂ξ^3)+b B ∂/(∂ξ)|B|^2+c|B|^2(∂B)/(∂ξ)=0,where B is the wave amplitude. Some stational solutions (bright solitons, kink solution, spiky soliton with rapid phase rotation) are discussed.
