Spectral asymptotics of a strong δ' interaction supported by a surface
Abstract
We derive asymptotic expansion for the spectrum of Hamiltonians with a strong attractive δ' interaction supported by a smooth surface in 3, either infinite and asymptotically planar, or compact and closed. Its second term is found to be determined by a Schr\"odinger type operator with an effective potential expressed in terms of the interaction support curvatures.
