Is there a solution or progress of the following problem (maybe old conjecture): Is An immersed surface with constant mean curvature and with a circle as a boundary is a part of a sphere??. If we replace "immersed" by "embedded" I think the problem is solvewas solved by Alexandroff kind of long time ago (maybe we have also to assume that the mean curvature is constant). Is someone could enlighten about what exactly Alexandroff solves and what is to do, it would help me a lot.

Thanks Mario
