Abstract
This paper concerns the modified fractional Korteweg-de Vries (modified fKdV) and fractional cubic nonlinear Schrödinger (fNLS) equations, with the dispersions and respectively. We prove the global existence of small solutions for both the Cauchy problems to the modified fKdV and fNLS equations, with a modified scattering which has a logarithmic phase correction. Our results cover the full range for both the modified fKdV and fNLS equations.

摘要
本文涉及修正分数 Korteweg-de Vries (修正 fKdV) 和分数三次非线性薛定谔 (fNLS) 方程,其离散度为 和 分别。我们证明了修正的 fKdV 和 fNLS 方程的柯西问题的小解的全局存在,并使用具有对数相位校正的修正散射。我们的结果涵盖所有范围 对于修改后的 fKdV 和 fNLS 方程。
