Examines lower bounds on multilinear operators with Gaussian kernels acting on Lebesgue spaces, with exponents below one. The authors put forward natural conditions when the optimal constant can be computed by inspecting centered Gaussian functions only, and we give necessary and sufficient conditions for this constant to be positive.
