Eigenvalues of Laplacian with constant magnetic field on non-compact hyperbolic surfaces with finite area
Abstract
We consider a magnetic Laplacian $-Δ_A=(id+A)^\star (id+A)$ on a noncompact hyperbolic surface $\mM $ with finite area. $A$ is a real one-form and the magnetic field $dA$ is constant in each cusp. When the harmonic component of $A$ satifies some quantified condition, the spectrum of $-Δ_A$ is discrete. In this case we prove that the counting function of the eigenvalues of $-Δ_{A}$ satisfies the classical Weyl formula, even when $dA=0. $
