- W2991467534 abstract "For $xi = (xi_1, xi_2, ldots, xi_d) in mathbb{R}^d$ let $Q(xi) := sum_{j=1}^d sigma_j xi_j^2$ be a quadratic form with signs $sigma_j in {pm1}$ not all equal. Let $S subset mathbb{R}^{d+1}$ be the hyperbolic paraboloid given by $S = big{(xi, tau) in mathbb{R}^{d}times mathbb{R} : tau = Q(xi)big}$. In this note we prove that Gaussians never extremize an $L^p(mathbb{R}^d) to L^{q}(mathbb{R}^{d+1})$ Fourier extension inequality associated to this surface." @default.
