摘要:

我们研究具有一般非线性项的时空分数阶非线性薛定谔方程的柯西问题。基于衰减估计和Hölder型估计,我们在分数阶Sobolev空间中证明了该问题的局部适定性。由于解算子缺乏半群结构,我们通过Mittag-Leffler函数和Bessel函数的渐近展开推导出衰减估计和Hölder型估计。特别地,这些结果也展示了解的色散性质。

英文摘要:

We study the Cauhcy problem for space-time fractional nonlinear Schrödinger equation with a general nonlinearity. We prove the local well-posedness of it in fractional Sobolev spaces based on the decay estimates and Hölder type estimates. Due to the lack of the semigroup structure of the solution operators, we deduce the decay estimates and Hölder type estimates via the asymptotic expansion of the Mittag-Leffler functions and Bessel functions. In particular, these results also show the dispersion of the solutions.
