Fractional nonlinear Schrödinger and Hartree equations in modulation spaces

Divyang G. Bhimani, Diksha Dhingra, Vijay Kumar Sohani

We establish global well-posedness for the mass subcritical nonlinear fractional Schrödinger equation $i u_{t} - (- Δ)^{\frac{β}{2}} u + F (u) = 0$ having radial initial data in modulation sp…

Low-regularity global solution of the inhomogeneous nonlinear Schrödinger equations in modulation spaces

Divyang G. Bhimani, Diksha Dhingra, Vijay Kumar Sohani

The study of low regularity Cauchy data for nonlinear dispersive PDEs has successfully been achieved using modulation spaces $M^{p, q}$ in recent years. In this paper, we study the…
