About gauge equivalent of the generalized Landau-Lifshitz equation
Вестник КазНУ. Серия математика, механика, информатика, 2017 In mathematics an inverse scattering transformation is a method for solving some nonlinear equations with partial derivatives. Discovering of the method became one of the crucial events in mathematical physics in the last 40 years [1]–[6].

Mixed spectral AKNS hierarchy from linear isospectral problem and its exact solutions
Open Physics, 2015 In this paper, the AKNS isospectral problem and its corresponding time evolution are generalized by embedding three coefficient functions. Starting from the generalizedAKNS isospectral problem, a mixed spectralAKNS hierarchy with variable coefficients is
