The sphere and the cut locus at a tangency point in two-dimensional almost-Riemannian geometry

open access: yes, 2010
We study the tangential case in 2-dimensional almost-Riemannian geometry. We analyse the connection with the Martinet case in sub-Riemannian geometry. We compute estimations of the exponential map which allow us to describe the conjugate locus and the ...

Geometry of Foliated Manifolds

open access: yesExtracta Mathematicae, 2016
In this paper some results of the authors on geometry of foliated manifolds are stated and results on geometry of Riemannian (metric) foliations are discussed.

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.

Riemannian Holonomy and Algebraic Geometry

open access: yes, 1999
This survey paper is devoted to Riemannian manifolds with special holonomy. To any Riemannian manifold of dimension n is associated a closed subgroup of SO(n), the holonomy group; this is one of the most basic invariants of the metric.
