Abstract: Based on the degenerate Darboux transformation, the n-order smooth positon solutions for the derivative nonlinear Schrodinger equation are generated by means of the general determinant expression of the N-soliton solution, and interesting dynamic behaviors of… read more here.

Abstract: In this paper, the smooth order-n positon solutions and b-positon solutions of the NLS-MB equation are constructed by the degenerate Darboux transformation (DT). The decomposition of the order-2, order-3, and order-4 positon solutions is discussed… read more here.
