TITLE On free boundary minimal annuli in a half-ball
ABSTRACT Free boundary minimal surfaces in a ball was first studied by Nitsche, who showed that the equatorial disk is a unique embedded free boundary minimal disk in a 3-dimensional Euclidean ball. In the same paper, Nitsche claimed the only embedded free boundary minimal annulus in a 3-dimensional Euclidean ball is congruent to the critical catenoid. In this talk, we consider Nitsche's claim for a half-ball and several characterizations of the critical catenoid.
