Localised variants of multilinear restriction
Article Sidebar
Main Article Content
We revisit certain localised variants of the Bennett–Carbery–Tao multilinear restriction theorem, recently proved by Bejenaru. We give a new proof of Bejenaru’s theorem, relating the estimates to the theory of Kakeya–Brascamp–Lieb inequalities. Moreover, the new proof allows for a substantial generalisation, exploiting the full power of the Kakeya–Brascamp–Lieb theory.
