Counting function of the embedded eigenvalues for some manifold with cusps, and magnetic Laplacian

Abderemane Morame, Francoise Truc

We consider a non compact, complete manifold {\bf{M}} of finite area with cuspidal ends. The generic cusp is isomorphic to $\mathbf{X}\times ]1,+\infty [$ with metric $ds^2=(h+dy^2)/…
