| contents | We consider the spatially inhomogeneous Landau equation in the case of very soft and Coulomb potentials, $γ\in [-3,-2]$. We show that solutions can be continued as long as the following three quantities remain finite, uniformly in $t$ and $x$: (1) the mass density, (2) the velocity moment of order $s$ for any small $s>0$, and (3) the $L^p_v$ norm for any $p>3/(5+γ)$. In particular, we do not require a bound on the energy density. |
