| contents | Under the coset formulation of pure Einstein spacetime, we solve the reduction problem of the nonlinear \(σ\)-model for this spacetime and present the process of the inverse scattering technique after simplification. Through the simplified inverse scattering process, taking the pure Rindler metric as the background, we introduce a pair of solitons on the imaginary axis and obtain an accelerating solution in the form of three solitons in this model. By means of appropriate parameter selection and coordinate transformation, we prove that this accelerating solution in the three-soliton formulation is equivalent to the accelerating Kerr solution. |
