Surfaces with constant curvature in S2×R and H2×R. Height estimates and representation

Surfaces with constant curvature in S2×R and H2×R. Height estimates and representation We obtain optimal height estimates for surfaces in ℍ2 × ℝ and $$ \mathbb{S}^{2} $$ × ℝ with constant Gaussian curvature K(I) and positive extrinsic curvature, characterizing the extreme cases as the revolution ones. Moreover, we get a representation for surfaces with constant Gaussian curvature in such ambient spaces, paying special attention to the cases of K(I) = 1 in $$ \mathbb{S}^{2} $$ × ℝ and K(I) = −1 in ℍ2 × ℝ. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of the Brazilian Mathematical Society, New Series Springer Journals

Abstract

We obtain optimal height estimates for surfaces in ℍ2 × ℝ and $$ \mathbb{S}^{2} $$ × ℝ with constant Gaussian curvature K(I) and positive extrinsic curvature, characterizing the extreme cases as the revolution ones. Moreover, we get a representation for surfaces with constant Gaussian curvature in such ambient spaces, paying special attention to the cases of K(I) = 1 in $$ \mathbb{S}^{2} $$ × ℝ and K(I) = −1 in ℍ2 × ℝ.
