Abstract
We prove L1(ℝ2)→L∞(ℝ2) for the two-dimensional Schrödinger operator −Δ+V with the decay rate t−1. We assume that zero energy is neither an eigenvalue nor a resonance. This condition is formulated as in the recent paper by Jensen and Nenciu on threshold expansions for the two-dimensional resolvent.
