Abstract

We apply geometric incidence estimates in positive characteristic to prove the optimal L²→L³ Fourier extension estimate for the paraboloid in the four-dimensional vector space over a prime residue field. In three dimensions, when −1 is not a square, we prove an L²→L^{[Formula presented]} extension estimate, improving the previously known exponent [Formula presented].
