Volume and Projection Inequalities I: Zonoids and Courtade's Conjecture
Matthieu Fradelizi, Alfredo Hubard, Auttawich Manui +3
We study volume and projection inequalities for zonoids through the multiaffine determinant polynomials that encode their volumes. We show that a log-submodularity conjecture for t…
Entropic analogues of Grünbaum's inequality
Matthieu Fradelizi, Lampros Gavalakis, Martin Rapaport
The classical Grünbaum inequality asserts that the proportion of the volume of a convex body cut off by a halfspace containing its barycenter is at least . From its functiona…
L_p-Rogers--Shephard type inequalities for L_p-zonoids and symmetric bodies
Matthieu Fradelizi, Auttawich Manui, Mark Meyer +1
We study generalizations of the classical Rogers--Shephard inequalities in the framework of Firey -summation. We first consider the class of asymmetric -zonoids. In this…
Equality cases for the -Rogers--Shephard inequality in the plane and for locally anti-blocking bodies in
Matthieu Fradelizi, Auttawich Manui, Mark Meyer +1
The classical Rogers--Shephard inequalities were extended to the Firey -summation by Bianchini and Colesanti in the plane and by Zvavitch and the second and fourth authors for…
Weighted Brunn-Minkowski Theory II: Inequalities for Mixed Measures and Applications
Matthieu Fradelizi, Dylan Langharst, Mokshay Madiman +1
In "Weighted Brunn-Minkowski Theory I", the prequel to this work, we discussed how recent developments on concavity of measures have laid the foundations of a nascent weighted Brun…
On the monotonicity of discrete entropy for log-concave random vectors on
Matthieu Fradelizi, Lampros Gavalakis, Martin Rapaport
We prove the following type of discrete entropy monotonicity for sums of isotropic, log-concave, independent and identically distributed random vectors on $\mat…
