On examples of duals Saito's basis of some inhomogeneous divisors, and application

Kamtila Kari, Joseph Dongho, Prosper Rosaire Mama Assandje +1

We investigate a class of non-quasi-homogeneous free divisors in the sense of Saito. These divisors are defined by equations of the form on , where the…

On Logit Weibull Manifold

Prosper Rosaire Mama Assandje, Joseph Dongho, Thomas Bouetou Bouetou

In this work, it is shown that there is no potential function on the Weilbull statistical manifold. However, from the two-parameter Weibull model we can extract a model with a pote…

Completely Integrable Gradient System on the bivariate beta statistical manifold

Prosper Rosaire Mama Assandje, Joseph Dongho, Thomas Bouetou Bouetou

This paper investigates the geometry of a completely integrable gradient system defined on the three parameter bivariate beta statistical manifold of the first kind. We prove that…

Riemannian curvature of gaussian distribution in dual coordinate system

Prosper Rosaire Mama Assandje, Dongho Joseph, Thomas Bouetou Bouetou

In this paper, we study the geometric nonlinearity properties, such as curvature and torsion, in a dual coordinate system of the Riemannian manifold defined by the Gaussian distrib…

A Kahlerian approche to the Schrodinger equation in Siegel jacobi Space of the lognormal distribution

Prosper Rosaire Mama Assandje, Joseph Dongho, Thomas Bouetou Bouetou

In this paper, we describe the evolution of spectral curves in the Siegel Jacobi space through the Schrodinger equation constructed from a Kahler geometry induced on the lognormal…

Schouten like metrics on five dimensional nilpotents Lie groups

Marius Landry Foka, Michel Bertrand Ngaha Djiadeu, Thomas Bouetou Bouetou

The prescribed Ricci curvature problem involves finding a Riemannian metric g that satisfies the equation ric(g) = T, where T is a fixed symmetric (0, 2)-tensor field on a differen…
