As is well known, no manifold of constant mean curvature 1 can exist in a domain strictly containing the unit ball. In part 1 of this paper, we shall consider the problem of estimating absolute apriori bounds for a manifold of constant mean curvature 1 in a ball of radius less than 1 without imposing boundary conditions or bounds of any sort in the higher dimensional case.It is also well-known that we may reduce the capillary problem in the absence of gravity to the variational problem for the functional E indicated in the beginning of 2.6.2. In case that a generalized solution for E exists, we consider the sets P and N where this generalized solution takes the value +∞ and −∞ respectively. Using the method in part 1, we shall, in part 2, try to characterize the geometry of the boundaries of P and N in the interior of the domain and ask whether they are spherical caps or not.
