Curvature estimates for graphs with prescribed mean curvature and flat normal bundle
Steffen Froehlich, Sven Winklmann
Abstract
We consider graphs Sigman in Rm with prescribed mean curvature and flat normal bundle. Using techniques of Schoen, Simon and Yau, and Ecker-Huisken, we derive an interior curvature estimate of the form |A|2<=C/R2 up to dimension n<=5, where C is a constant depending on natural geometric data of Sigman only. This generalizes previous results of Smoczyk, Wang and Xin, and Wang for minimal graphs with flat normal bundle.
