Abstract
The Landau equation is studied for hard potential with −2 ≤ γ ≤ 1. Under a perturbation setting, a unique global solution of the Cauchy problem to the Landau equation is established in a critical Sobolev space \(H_x^dL_v^2(d > {3 \over 2})\), which extends the results of [11] in the torus domain to the whole space \(\mathbb{R}_x^3\). Here we utilize the pseudo-differential calculus to derive our desired result.
