S-Curvature, E-Curvature, and Berwald Scalar Curvature of Finsler Spaces

Differential Geometry and its Applications, 2023
This paper deals with the study of \(S\)-curvature, \(E\)-curvature and Berwald scalar curvature for Finsler spaces. More exactly, the author proves that the \(S\)-curvature of a Finsler space vanishes if and only if the \(E\)-curvature vanishes if and only if the Berwald scalar curvature vanishes.

Penile Curvatures

Plastic and Reconstructive Surgery, 1985
Penile curvatures are common. They are caused by tethering inelastic tissues that can be from the skin externally, from the congenital fibrous tissue of hypospadias and epispadias, and from inelastic tunica albuginea as in fractures, trauma, or Peyronie's disease.

Curvature Symmetries

Acta Applicandae Mathematica, 2001
This paper is the new section 5 of the author's paper ``Affine connection complexes'', which appeared ibid. 59, 215-227 (1999; Zbl 0956.53014). Here is given the proof of Proposition 5.4.: The Riemannian curvature tensor \(R(g)\in\otimes^4\varepsilon\) of any Riemannian manifold \((M,g)\) is a symmetric element of the submodule \(A^2\varepsilon\otimes ...

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.

Establishing functional correlations between multiscale areal curvatures and coefficients of friction for machined surfaces

Surface Topography Metrology and Properties, 2018
The objective of this research is to determine the strengths of correlation, and their variation with scale, between friction coefficients and topographic characterization parameters, calculated using statistical representations of multiscale areal ...

Riemann Curvature and Ricci Curvature

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.

Inequalities for Algebraic Casorati Curvatures and Their Applications II

, 2016
Different kind of algebraic Casorati curvatures are introduced. A result expressing basic Casorati inequalities for algebraic Casorati curvatures is presented and equality cases are discussed.

Douglas Curvature and Weyl Curvature

2001
There are two important projective invariants of sprays and Finsler metrics. One is a non-Riemannian projective invariant constructed from the Berwald curvature. The other is a Riemannian projective invariant constructed from the Riemann curvature. In this chapter, we will discuss these two projective invariants.
