我们证明了一个不等式,并将其应用于薛定谔方程的解。存在一个普适常数c > 0,使得如果Ω 2是单连通的,则Ω→ Ω上消失,并且|u|假设在x 0 ∈Ω中有极大值,则infy∈ <$Ω <$$> x 0 −y <$$> ≥c <$Δuu <$L∞(Ω)−1/2。
We prove an inequality with applications to solutions of the Schrödinger equation. There is a universal constant c > 0 such that if Ω⊂ℝ2 is simply connected, Ω→ℝ vanishes on the boundary ∂Ω, and |u| assumes a maximum in x0∈Ω , then infy∈∂Ω‖‖ x0−y ‖‖≥c‖ Δuu ‖L∞(Ω)−1/2.
