A posteriori error estimator for the eigenvalue problem associated to the Schrödinger operator with magnetic field
The paper is devoted to the eigenvalue problem associated to the Schrödinger operator with constant magnetic field on a polygonal set in \(\mathbb R^2\). The author proposes an formulation of a a posteriori error estimates without using the dual problem. Obtained an a posteriori error estimate is appropriate to improve numerical computations by using adaptive mesh-refinement techniques. Numerical tests are given.
