Nonlocal Symmetries, Consistent Riccati Expansion Solvability and Interaction Solutions of the Generalized Ito Equation

In this paper, we investigate the generalized Ito equation. By using the truncated Painlevé analysis method, we successfully derive its nonlocal symmetry and Bäcklund transformation, respectively. By introducing new dependent variables for the nonlocal symmetry, we find the corresponding Lie point symmetry. Moreover, we construct the interaction solution between soliton and cnoidal periodic wave of the equation by considering the consistent tanh expansion method. The conservation laws of the equation are also obtained with a detailed derivation.
