An estimate for the sectional curvature of cylindrically bounded submanifolds
arXiv:0907.5025
Abstract
We give sharp sectional curvature estimates for complete immersed cylindrically bounded -submanifolds , provided that either is proper with the second fundamental form with certain controlled growth or has scalar curvature with strong quadratic decay. This latter gives a non-trivial extension of the Jorge-Koutrofiotis Theorem [7]
