On the Curvatures of a Surface

American Journal of Mathematics, 1953
1. The smoothness of H and K. A point set 8 in the (x, y, z) -space is said to be a (small piece of a) surface of class Gn, where n ^ 1, if it is the locus of the endpoints of a vector function X = X(u,v) with three com? ponents which is defined on a two-dimensional (u, v) -domain, possesses con?

Riemann Curvature and Ricci Curvature [PDF]

open access: possible, 2012
Curvatures are the central concept in geometry. The notion of curvature introduced by B. Riemann faithfully reveals the local geometric properties of a Riemann metric. This curvature is called the Riemann curvature in Riemannian geometry. The Riemann curvature can be extended to Finsler metrics as well as the sectional curvature.

Structural curvature versus amplitude curvature

The Leading Edge, 2011
Because they are second-order derivatives, seismic curvature attributes can enhance subtle information that may be difficult to see using first-order derivatives such as the dip magnitude and the dip-azimuth attributes. As a result, these attributes form an integral part of most seismic interpretation projects.
