报告摘要:The modified Camassa-Holm equation (mCH) with a cubic nonlinearity is an integrabel and nonlocal mathematical model for the unidirectional propagation of shallow-water waves. This study establishes the existence of time-periodic, spatially localized smooth-wave solutions, known as breathers, within a specific range of the linear dispersive parameter. By employing three rarely used conserved quantities, expressed in terms of the momentum variable m, it is demonstrated that breathers, as solutions to the mCH equation, are orbitally stable under perturbations in the Sobolev space H^2.
