论文摘要
本文涉及经过修改的分数Korteweg-de Vries(修饰的FKDV)和非线性Schrödinger(修改的FNLS)方程,分别分别| d |^α\ partial_x和| d | d |^{α+1}。我们证明了针对修饰的FKDV和FNLS方程的库奇问题的全球溶液存在,并具有具有对数相校正的修改散射。我们的结果涵盖了修改后的FKDV和FNLS方程的全范围-1 <α<1,α\ neq 0。
This paper concerns the modified fractional Korteweg-de Vries (modified fKdV) and nonlinear Schrödinger (modified fNLS) equations, with the dispersions |D|^α\partial_x and |D|^{α+1}, 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 -1<α<1, α\neq 0 for both the modified fKdV and fNLS equations.
