Scattering and blow-up dichotomy of the energy-critical nonlinear Schrödinger equation with the inverse-square potential

Masaru Hamano, Masahiro Ikeda

In this paper, we consider the energy critical nonlinear Schrödinger equation with a repulsive inverse square potential. In particular, we deal with radial initial data, whose ener…
