Covariance inequalities for convex and log-concave functions

Michel Bonnefont, Erwan Hillion, Adrien Saumard

Extending results of Harg{é} and Hu for the Gaussian measure, we prove inequalities for the covariance Cov where is a general product probability measure on $\mathbb{…

A proof of the Shepp-Olkin entropy monotonicity conjecture

Erwan Hillion, Oliver Johnson

Consider tossing a collection of coins, each fair or biased towards heads, and take the distribution of the total number of heads that result. It is natural to conjecture that this…

An extremal property of the normal distribution, with a discrete analog

Erwan Hillion, Oliver Johnson, Adrien Saumard

We prove, using the Brascamp-Lieb inequality, that the Gaussian measure is the only strong log-concave measure having a strong log-concavity parameter equal to its covariance matri…

A proof of the Shepp-Olkin entropy concavity conjecture

Erwan Hillion, Oliver Johnson

We prove the Shepp--Olkin conjecture, which states that the entropy of the sum of independent Bernoulli random variables is concave in the parameters of the individual random varia…

Entropy along W_{1,+}-geodesics on graphs

Erwan Hillion

We study the convexity of the entropy functional along particular interpolating curves defined on the space of finitely supported probability measures on a graph.

-interpolation of probability measures on graphs

Erwan Hillion

We generalize an equation introduced by Benamou and Brenier, characterizing Wasserstein W_p-geodesics for p > 1, from the continuous setting of probability distributions on a Riema…

Discrete versions of the transport equation and the Shepp-Olkin conjecture

Erwan Hillion, Oliver Johnson

We introduce a framework to consider transport problems for integer-valued random variables. We introduce weighting coefficients which allow us to characterize transport problems i…

A natural derivative on [0,n] and a binomial Poincaré inequality

Erwan Hillion, Oliver Johnson, Yaming Yu

We consider probability measures supported on a finite discrete interval . We introduce a new finitedifference operator , defined as a linear combination of left a…
