The analytic Gelfand-Shilov smoothing effect of the Landau equation with hard potential

Inthispaper,westudytheCauchyproblemoftheinhomogeneous Landau equation with hard potentials under the perturbation framework to global equilibrium. We prove that the solution to the Cauchy problem enjoys the analytic Gelfand-Shilov regularizing effect with a Sobolev initial datum for positive time.
