Multilinear Duality and Factorisation for Brascamp--Lieb-type Inequalities with applications

  title={Multilinear Duality and Factorisation for Brascamp--Lieb-type Inequalities with applications},

  journal={arXiv: Functional Analysis},
We initiate the study of a duality theory which applies to norm inequalities for pointwise weighted geometric means of positive operators. The theory finds its expression in terms of certain pointwise factorisation properties of function spaces which are naturally associated to the norm inequality under consideration. We relate our theory to the Maurey--Nikisin--Stein theory of factorisation of operators, and present a fully multilinear version of Maurey's fundamental theorem on factorisation… Expand
A variational proof of a disentanglement theorem for multilinear norm inequalities
Abstract. In [1] and [2] we developed a duality theory for multilinear norm inequalities. This duality theory is underpinned by a disentanglement theorem, which states that estimates on a weightedExpand
A Nonlinear Variant of Ball's Inequality
We adapt a recent induction-on-scales argument of Bennett, Bez, Buschenhenke, Cowling, and Flock to establish a global near-monotonicity statement for the nonlinear Brascamp–Lieb functional under aExpand
Disentanglement, Multilinear Duality and Factorisation for non-positive operators
In previous work we established a multilinear duality and factorisation theory for norm inequalities for pointwise weighted geometric means of positive linear operators defined on normed lattices. InExpand
Five-Linear Singular Integral Estimates of Brascamp-Lieb Type.
We prove the full range of estimates for a five-linear singular integral of Brascamp-Lieb type. The study is methodology-oriented with the goal to develop a sufficiently general technique to estimateExpand
On affine invariant and local Loomis–Whitney type inequalities
We prove various extensions of the Loomis-Whitney inequality and its dual, where the subspaces on which the projections (or sections) are considered are either spanned by vectors $w_i$ of a notExpand


The Brascamp–Lieb Inequalities: Finiteness, Structure and Extremals
Abstract.We consider the Brascamp–Lieb inequalities concerning multilinear integrals of products of functions in several dimensions. We give a complete treatment of the issues of finiteness of theExpand
Factorization of positive multilinear maps
For an excellent survey of these theorems and the many applications of them we refer to J. E. Gilbert’s paper [2]. In this same article Gilbert indicates that there are available versions ofExpand
A Generalization of Holder's Inequality and Some Probability Inequalities
The main result of this article is a generalization of the generalized Holder inequality for functions or random variables defined on lowerdimensional subspaces of n-dimensional product spaces. ItExpand
On the Schrödinger maximal function in higher dimension
AbstractNew estimates on the maximal function associated to the linear Schrödinger equation are established. It is shown that the almost everywhere convergence property of eitΔf for t → 0 holds for fExpand
The Brascamp–Lieb Polyhedron
Abstract A set of necessary and sufficient conditions for the Brascamp–Lieb inequality to hold has recently been found by Bennett, Carbery, Christ, and Tao. We present an analysis of theseExpand
Complex interpolation and regular operators between Banach lattices
We study certain interpolation and extension properties of the space of regular operators between two Banach lattices. Let R p be the space of all the regular (or equivalently order bounded)Expand
Factoring multi-sublinear maps
Abstract Using Rademacher type, maximal estimates are established for k-sublinear operators with values in the space of measurable functions. Maurey–Nikishin factorization implies that such operatorsExpand
Bounds on Oscillatory Integral Operators Based on Multilinear Estimates
We apply the Bennett–Carbery–Tao multilinear restriction estimate in order to bound restriction operators and more general oscillatory integral operators. We get improved Lp estimates in the SteinExpand
Finitely additive measures
0. Introduction. The present paper is concerned with real-valued measures which enjoy the property of finite additivity but not necessarily the property of countable additivity. Our interest in suchExpand

We prove d-linear analogues of the classical restriction and Kakeya conjectures in Rd. Our approach involves obtaining monotonicity formulae pertaining to a certain evolution of families ofExpand
