报告摘要

This work studies a   generalized µ-type integrable equation with both quadratic and cubic   nonlinearities; the µ-Camassa-Holm and modified µ-Camassa-Holm equations are   members of this family of equations. It has been shown that the Cauchy   problem for this generalized µ-Camassa-Holm integrable equation is locally   well-posed for initial

data u0 belongs to Hs, s   > 5/2. In this work, we further investigate the continuity properties to this   equation. It is proved in this work that the data-to-solution map of the   proposed quation is not uniformly continuous. It is also found that the   solution map is Holder continuous in the Hr-topology when 0  r < s with Holder   exponent α depending on both   s and r.
