Observability for the Schrödinger Equation in a Uniform Magnetic Field
摘要
We prove the observability inequalities at two time points for the Schrödinger equation in a uniform magnetic field in dimensions 2 and 3. The proofs mainly rely on Nazarov’s uncertainty principle. In particular, the observability inequality in three dimensions can also be derived from the approach used to establish the Amerin–Berthier uncertainty principle.
