The Bäcklund transformations and the superposition formulas for two subequations of the general elliptic equation are constructed from the Riccati equation by using an indirect mapping method. The thirty-six previously known solutions of the general elliptic equation are proved to be equivalent to the another ten solutions. The classification of solutions for the general elliptic equation is obtained based on the equivalence relations. The general elliptic equation expansion method with new classified solutions are used to obtain abundant new exact traveling wave solutions of a modified Camassa-Holm equation.

This paper is concerned with the global solutions for the modified Camassa-Holm equation. We first obtain the global existence and uniqueness of strong solutions for the initial datum 𝑢 0 (𝑥) ∈ 𝐻 𝑠 (ℝ) with 𝑠 > 3∕2, and then give some norm estimates of strong solutions and its momentum density. Finally, by using the compensated compactness method and regularization technique, we establish the global existence and uniqueness of weak solutions for the initial datum 𝑢 0 (𝑥) ∈ 𝐻 1 (ℝ).
