Abstract

Let M be an n-dimensional complete simply connected Riemannian manifold with sectional curvature bounded above by a nonpositive constant . Using the cone total curvature TC() of a graph which was introduced by Gulliver and Yamada [8], we prove that the density at any point of a soap film-like surface spanning a graph is less than or equal to . From this density estimate we obtain the regularity theorems for soap film-like surfaces spanning graphs with small total curvature. In particular, when n
