 On the orbital stability of inhomogeneous nonlinear Schr\"{o}dinger equations with singular potential Bull. Korean Math. Soc.Published online June 10, 2019 Yonggeun Cho and Misung Lee Chonbuk National University Abstract : We show the existence of ground state and orbital stability of standing waves of nonlinear Schr\"{o}dinger equations with singular linear potential and essentially mass-subcritical power type nonlinearity. For this purpose we establish the existence of ground state in $H^1$. We do not assume symmetry or monotonicity. We also consider local and global well-posedness of Strichartz solutions of energy-subcritical equations. We improve the range of inhomogeneous coefficient in \cite{guz} in 2 and 3 dimensions. Keywords : inhomogeneous NLS, singular potential, ground state, orbital stability, well-posedness, Strichartz solution MSC numbers : 33Q40, 35Q55 Full-Text :
