Curvature tensor - Open Access .click

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2005
Although curvature estimation from a given mesh or regularly sampled point set is a well-studied problem, it is still challenging when the input consists of a cloud of unstructured points corrupted by misalignment error and outlier noise. Such input is ubiquitous in computer vision.

Curvature tensors and curvature conditions in Weyl geometry

Commentarii mathematici Universitatis Sancti Pauli = Rikkyo Daigaku sugaku zasshi, 1994
A Weyl structure on a manifold \(M\) is a system \(D = (C, \nabla)\) where \(C\) is a conformal class of metrics on \(M\) and \(\nabla\) a fixed Weyl connection. Then for each metric \(g \in C\) there exists a unique 1-form \(\phi_g\) on \(M\) such that \(\nabla g = 2\phi_g \otimes g\). By analogy with the Riemannian case [\textit{A. L.

The length of curvature tensor for Riemannian manifold with parallel Ricci curvature tensor

Publicationes Mathematicae Debrecen, 2011
In this paper, we study compact Riemannian manifolds with Þ2Ric=0, and estab- lish a pinching theorem for the square of the length of Riemannian curvature tensor. When n . 10, the pinching constant is sharp.
