Abstract

In this work, we study the linearized Landau equation with soft potentials and show that the smooth solution to the Cauchy problem with initial datum in $L^{2}(\mathbb{R}^3)$ enjoys an analytic regularization effect, and that the evolution of the analytic radius is the same as the heat equations.
