Abstract/Media

We show that ellipses of sufficiently small eccentricity are spectrally unique among all smooth planar domains. This is the first unconditional inverse spectral result for plane domains since Kac's result that disks are spectrally determined among all domains.  This is a joint work with Steve Zelditch.
