Finsler geometry on higher order tensor fields and applications to high angular resolution diffusion imaging. [PDF]

open access: yes, 2009
We study 3D-multidirectional images, using Finsler geometry. The application considered here is in medical image analysis, specifically in High Angular Resolution Diffusion Imaging (HARDI) (Tuch et al. in Magn. Reson. Med.

Integrable Equations and Their Evolutions Based on Intrinsic Geometry of Riemann Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
The intrinsic geometry of surfaces and Riemannian spaces will be investigated. It is shown that many nonlinear partial differential equations with physical applications and soliton solutions can be determined from the components of the relevant metric ...

The volume entropy of a surface decreases along the Ricci flow [PDF]

open access: yes, 2004
The volume entropy, h(g), of a compact Riemannian manifold (M,g) measures the growth rate of the volume of a ball of radius R in its universal cover.

An introduction to Smarandache multi-spaces and mathematical combinatorics [PDF]

open access: yes, 2007
These Smarandache spaces are right theories for objectives by logic. However, the mathematical combinatorics is a combinatorial theory for branches in classical mathematics motivated by a combinatorial speculation.

NULL AND INFINITESIMAL ISOTROPY IN SEMI-RIEMANNIAN GEOMETRY

open access: yes, 1994
Null and infinitesimal isotropy are defined for semi-Riemannian manifolds in a more general context. A theorem of Karcher is extended to semi-Riemannian manifolds in a more general setting.

Combinatorial Optimization with Information Geometry: The Newton Method

open access: yesEntropy, 2014
e discuss the use of the Newton method in the computation of max(p → Εp [f]), where p belongs to a statistical exponential family on a finite state space.

Applications of Riemannian Submersions

open access: yes, 2017
In this chapter, we give two applications of Riemannian submersions and it consists of two sections. In the first section, we give an application of Riemannian submersions in robotic theory [12].
