摘要

我们研究了朗道方程的正则化版本，该版本最近在~\cite{CHWW20}中引入，以在合理的计算成本下以良好的精度对朗道方程进行数值近似。我们发展了弱解的存在唯一性理论，并通过严格证明正则化Landau方程的粒子近似的有效性，加强了~\cite{CHWW20}中的数值发现。

Convergence of a particle method for a regularized spatially homogeneous Landau equation

We study a regularized version of the Landau equation, which was recently introduced in~\cite{CHWW20} to numerically approximate the Landau equation with good accuracy at reasonable computational cost. We develop the existence and uniqueness theory for weak solutions, and we reinforce the numerical findings in~\cite{CHWW20} by rigorously proving the validity of particle approximations to the regularized Landau equation.
