WebAbstract. We show that if the eccentricity of an ellipse is sufficiently small, then up to isometries it is spectrally unique among all smooth domains. We do not assume any symmetry, convexity, or closeness to the ellipse, on the class of domains. In the course of the proof we also show that for nearly circular domains, the lengths of periodic ...
