Global well-posedness and scattering for the defocusing nonlinear Schrödinger equation below energy space

In this paper, we prove global well-posedness and scattering below the energy space for the defocusing nonlinear Schrödinger equation with intercritical power nonlinearities in spatial dimensions $d\ge 3$, improving the regularity threshold of Vişan and Zhang [Differ. Integr. Equations, 22(2009), 99-124].
