Deformation of affine structures and the cohomology of Koszul-Vinberg algebras on the lie groups SO(2), H3(R) and Galilei group SGal(3)

Prosper R. Mama Assandje, R. Nimpa Pefoukeu, Michel B. Djiadeu Ngaha +2

In this work, we compare the De Rham cohomology and the Koszul-Vinberg cohomology groups on the Lie groups SO(2), H3(R) and SGal(3). We model their interactions by constructing a t…

Souriau-Fisher metric and Completely integrable system on Lie groups SO(2) and SO(3)

Prosper Rosaire Mama Assandje, Michel Bertrand Djiadeu Ngaha, Romain Nimpa Pefoukeu +1

We study the generalize Fisher metric on SO(2) and SO(3) via the thermodynamics Lie group theories of Souriau. Then we give the effect of 2-cocycle on the integrability of gradient…

A Hamiltonian driven Geometric Construction of Neural Networks via the Lognormal family, Application to Financial Fraud Detection and to Network Security

Prosper Rosaire Mama Assandje, Teumsa Aboubakar, Landry Foka Marius +5

We presents a method for constructing neural networks intrinsically on statistical manifolds via the lognormal distribution. We demonstrate this approach by formulating a neural ne…

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…

Deformation quantization of a hessian KV- structure on

Herguey Mopeng, Prosper Rosaire Mama Assandje, Joseph Dongho +1

This paper studies the quantization of the deformation of Hessian structures on a two-dimensional vector space, in the framework of Koszul-Vinberg algebras. We analyze how Hessian…
