Magnification inferred curvature for real-time curvature monitoring

Real-time Curvature Estimation on Deformable Models

Surface curvature and its derivative are used in a number of applications including non-photorealistic line drawing techniques. CPU algorithms for estimating curvature are a reasonable choice for static models, but curvature estimates for deformable models must be recomputed every frame. For many deformable models, for example those using vertex blending, the deformed model is only ever present...

Landsberg Curvature, S-curvature and Riemann Curvature

Symmetric curvature tensor

Recently, we have used the symmetric bracket of vector fields, and developed the notion of the symmetric derivation. Using this machinery, we have defined the concept of symmetric curvature. This concept is natural and is related to the notions divergence and Laplacian of vector fields. This concept is also related to the derivations on the algebra of symmetric forms which has been discu...

CONNECTIONS, CURVATURE, AND p-CURVATURE

1.1. Connections and derivations. Let S be a scheme, and X smooth and finite type over S throughout. We have the rank-n vector bundle ΩX/S of 1-forms on X over S. We also fix some notation in the case that S is of characteristic p: in this case, we denote by FT the absolute Frobenius map for any scheme T , by X = X×S S the p-twist of X over S, where the map used in the fiber product is FS : S →...
