%0 Journal Article %T Asymptotic behavior of eigenvalues of Schr£żdinger type operators with degenerate kinetic energy %A Christian Hainzl %A Robert Seiringer %J Mathematics %D 2008 %I arXiv %X We study the eigenvalues of Schr\"odinger type operators $T + \lambda V$ and their asymptotic behavior in the small coupling limit $\lambda \to 0$, in the case where the symbol of the kinetic energy, $T(p)$, strongly degenerates on a non-trivial manifold of codimension one. %U http://arxiv.org/abs/0808.3737v1
