On Logarithmic Poisson and De Rham Cohomology Groups of a Class of Inhomogeneous Divisors
Kamtila Kari, Dongho Joseph, Diekouam Fotso Luc Emery
We study logarithmic Poisson and de Rham cohomologies associated with a class of inhomogeneous free divisors in the affine plane. These divisors arise as inhomogeneous deformations…

On logarithmic Poisson cohomology of a degenerate Poisson bivector in affine plane
Kamtila Kari, Iskamlé Bruno, Diekouam Fotso Luc Éméry +1
In this paper, we show that for a given degenerate bivector with , the classical Poisson cohomology group and the logarithmic Poisson coho…
