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

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
