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 in recent years. In this paper, we study the…
