WebMar 19, 2014 · We provide two types of upper bounds for the critical current where such global stability is achieved: by using the principal eigenvalue of the magnetic Laplacian associated with the normal magnetic field, and through the norm of the resolvent of the linearized steady-state operator. WebThe purpose of this note is to revisit the proof of the Gearhardt-Prüss-Hwang-Greiner theorem for a semigroup S (t), following the general idea of the proofs that we have seen in the literature and to get an explicit estimate on the norm of S (t) in terms of bounds on the resolvent of the generator.
