On affine invariant and local Loomis–Whitney type inequalities

Alonso Gutiérrez, David (Universidad de Zaragoza) ; Bernués, Julio (Universidad de Zaragoza) ; Brazitikos, Silouanos ; Carbery, Anthony

Resumen: 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 not necessarily orthonormal basis of $\mathbb{R^n}$ , or their orthogonal complements. In order to prove such inequalities, we estimate the constant in the Brascamp–Lieb inequality in terms of the vectors $w_i$ . Restricted and functional versions of the inequality will also be considered.
