A HEIGHT ESTIMATE FOR H-SURFACES AND EXISTENCE OF H-GRAPHS By SEBASTIÁN MONTIEL
نویسنده
چکیده
Let Ω be a bounded planar domain which is convex (although not necessarily strictly convex) with area A. We prove that, for each real number H satisfying AH2 < 2 , with = ( p 5 1)=2, there exists a graph on Ω with constant mean curvature H and boundary @Ω. This existence theorem is deduced as a consequence of an L estimate for compact constant mean curvature surfaces with planar boundary, in terms of the L1 norm of a component of its Gauss map, which will be obtained in this paper.

HEIGHT ESTIMATE FOR SPECIAL WEINGARTEN SURFACES OF ELLIPTIC TYPE IN M(c)× R
In this article we provide a vertical height estimate for compact special Weingarten surfaces of elliptic type in M2(c) × R, i.e. surfaces whose mean curvature H and extrinsic Gauss curvature Ke satisfy H = f(H2 −Ke) with 4x(f ′(x))2 < 1, for all x ∈ [0,+∞). The vertical height estimate generalizes a result by Rosenberg and Sa Earp and applies only to surfaces verifying a height estimate condit...
متن کاملExistence of constant mean curvature graphs in hyperbolic space
We give an existence result for constant mean curvature graphs in hyperbolic space Hn+1. Let Ω be a compact domain of a horosphere in Hn+1 whose boundary ∂Ω is mean convex, that is, its mean curvature H∂Ω (as a submanifold of the horosphere) is positive with respect to the inner orientation. If H is a number such that −H∂Ω < H < 1, then there exists a graph over Ω with constant mean curvature H...
متن کاملObstructions to the Existence of Smooth Solutions to the Plateau Problem in H1
In this paper we investigate H-minimal graphs of lower regularity. We show that noncharactersitic C H-minimal graphs are ruled surfaces with C seed curves. Moreover, in light of a structure theorem of Franchi, Serapioni and Serra Cassano, we see that any H-minimal surface is, up to a set of perimeter zero, composed of such pieces. Along these lines, we investigate ways in which patches of C H-m...
متن کاملA young girl with H syndrome and coeliac disease
H syndrome is an autosomal recessive genodermatosis with reports dating back to the last decade. This syndrome is caused by mutations in the SCL29A3 gene. The clinical characteristics of this syndrome consist of dermatological manifestations, including hyperpigmented, hypertrichotic, and indurated patches and plaques. It affects various systems by causing heart anomalies, hepatosplenomegaly, hy...
