$L^p$ estimates for the biest I. The Walsh case

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/60925We prove L^p estimates for the Walsh model of the "biest", a trilinear multiplier with singular symbol which arises naturally in the expansion of eigenfunctions of a Schrodinger operator, and which is also related to the bilinear Hilbert transform. The corresponding estimates for the Fourier model will be obtained in the sequel of this paper.22 pages, 1 figure, submitted, Math.
