摘要
We consider curvature-induced resonances in a planar two-dimensional Dirichlet tube of a width d. It is shown that the distances of the corresponding resonance poles from the real axis are exponentially small as d --> 0+, provided the curvature of the strip axis, satisfies certain analyticity and decay requirements.
