Isoperimetry for spherically symmetric log-concave probability measures

Nolwen Huet

We prove an isoperimetric inequality for probability measures $μ$ on $R^{n}$ with density proportional to $exp (- ϕ (λ ∣ x ∣))$ , where $∣ x ∣$ is the euclidean norm on $\mathbb{R}…

On Gaussian Brunn-Minkowski inequalities

Franck Barthe, Nolwen Huet

In this paper, we are interested in Gaussian versions of the classical Brunn-Minkowski inequality. We prove in a streamlined way a semigroup version of the Ehrard inequality for $m…

The hypergroup property and representation of Markov kernels

Dominique Bakry, Nolwen Huet

For a given orthonormal basis $(f_{n})$ on a probability measure space, we want to describe all Markov operators which have the $f_{n}$ as eigenvectors. We introduce for that what we c…
