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. | ||
