“…Moreover, according to [13], no solution is dispersive for λ < 0, while for λ > 0, solutions have a dispersive behavior (with a nonstandard rate of dispersion). It is noteworthy that there has been a growing recent interest in the LogSE with a potential V (x), where (∆ + V )u is in place of ∆u in (1.1) (see, e.g., [3,12,14,18,30,33]).…”
