Dispersive estimates for the Schrödinger equation with finite rank perturbations

Han Cheng, Shanlin Huang, Quan Zheng

In this paper, we investigate dispersive estimates for the time evolution of Hamiltonians $$ H=-Δ+\sum_{j=1}^N\langle\cdot\,, φ_j\rangle φ_j\quad\,\,\,\text{in}\,\,\,\mathbb{R}^d,\…
