我们证明了-qu + vu =λu的量子,其中λ∈ℂ和v和w是满足| v(x)|是非零,有限的,u(0)= 1,然后m(r)≳ Exp(-crβ0(log r)A(r),在n,p和λ的某些条件下,我们构建了示例(其中一些是Meshkov的样式),证明了M(R)的估计值为⟩ -p和| u(x)|
We prove quantitative unique continuation results for solutions of −Δu + W · ∇u + Vu = λu, where λ ∈ ℂ and V and W are complex-valued decaying potentials that satisfy |V(x)| < ⟨x⟩−N and |W(x)| < ⟨x⟩−P . For M(R) = inf|x 0| = R ‖u‖ L 2(B 1(x 0)), we show that if the solution u is non-zero, bounded, and u(0) = 1, then M(R) ≳ exp(−CR β0 (log R) A(R)), where . Under certain conditions on N, P and λ, we construct examples (some of which are in the style of Meshkov) to prove that this estimate for M(R) is sharp. That is, we construct functions u, V and W such that −Δu + W · ∇u + Vu = λu, |V(x)| < ⟨x⟩−N , |W(x)| < ⟨x⟩−P and |u(x)|
