Asymptotic behavior of solutions to a dissipative nonlinear Schr\"odinger equation with time dependent harmonic potentials
We consider the Cauchy problem of a dissipative nonlinear Schr\"odinger equation with a time dependent harmonic potential. We find a critical situation that the $L^2$-norm of dissipative solutions decays or not and which is decided by a nonlinear power and time decay order of harmonic potential.
