报告摘要:We prove that the trigonometric periodic peakons for the modified Camassa-Holm equation are orbitally stable. The proof is inspired by [A. Constantin, W. Strauss, Comm. Pure. Appl. Math. 53 (2000)603-610] where the case of peakons of the Camassa-Holm is considered. The main difficulty is that in [A. Constantin, W. Strauss, Comm. Pure. Appl. Math. 53 (2000)603-610] the function F_u associated with a solution u(x, t) could be chosen to be independent of time, whereas here the function F_u(t) depends on time. We solve this problem by establishing a key equality and two inequalities associated with three conservation laws. Our approach can also be applied to stability of elliptic periodic peakons.
