In this paper we obtain several results concerning the optimization of higher Steklov eigenvalues both in two and higher dimensional cases. We first show that the normalized (by boundary length)k-th Steklov eigenvalue on the disk is not maximized for a smooth metric on the disk for. Forthe classical result of Weinstock (J Ration Mech Anal 3:745–753, 1954) shows thatis maximized by the standard metric on the round disk. Forit was shown by Girouard and Polterovich (Funct Anal Appl 44(2):106–117, 2010) thatis not maximized for a smooth metric. We also prove a local rigidity result for the critical catenoid and the critical Möbius band as free boundary minimal surfaces in a ball underdeformations. We next show that the firstkSteklov eigenvalues are continuous under certain degenerations of Riemannian manifolds in any dimension. Finally we show that forthe supremum of thek-th Steklov eigenvalue on the annulus over all metrics is strictly larger that that over-invariant metrics. We prove this same result for metrics on the Möbius band.
