A comment about the paper On the instability of elliptic traveling wave solutions of the modified Camassa-Holm equation
arXiv:1912.06599
Abstract
We discuss the recent paper by A. Darós and L.K. Arruda (On the instability of elliptic traveling wave solutions of the modified Camassa-Holm equation, J. Diff. Equat., 266 (2019), 1946-1968). Our intention is to correct some imperfections left by the authors and present the orbital stability of periodic snoidal waves in the energy space.
