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.

Parallel Spinors on Pseudo-Riemannian Spin C Manifolds [PDF]

open access: yesarXiv, 2004
We describe, by their holonomy groups, all complete simply connected irreducible non-locally symmetric pseudo-Riemannian SpinC manifolds which admit parallel spinors. So we generalize the Riemannian SpinC case and the pseudo-Riemannian Spin one.

Some elementary observations regarding reductive Cartan geometries

open access: yes, 2016
After defining generalizations of the notions of covariant derivatives and geodesics from Riemannian geometry for reductive Cartan geometries in general, various results for reductive Cartan geometries analogous to important elementary results from ...

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 ...
