On Aharonov–Bohm Operators with Two Colliding Poles [PDF]
Advanced Nonlinear Studies, 2017 We consider Aharonov–Bohm operators with two poles and prove sharp asymptotics for simple eigenvalues as the poles collapse at an interior point out of nodal lines of the limit eigenfunction.

On Duclos–Exner’s conjecture about waveguides in strong uniform magnetic fields
Forum of Mathematics, Sigma, 2023 We consider the Dirichlet Laplacian with uniform magnetic field on a curved strip in two dimensions. We give a sufficient condition on the width and the curvature of the strip ensuring the existence of the discrete spectrum in the strong magnetic field ...

Dirichlet Eigenvalue Problem of Degenerate Elliptic Operators with Non-Smooth Coefficients
Communications in Mathematical Research, 2022 The aim of this review is to introduce some recent results in eigenvalues problems for a class of degenerate elliptic operators with non-smooth coefficients, we present the explicit estimates of the lower bound and upper bound for its Dirichlet ...
