论文摘要
我们给出了一个简单的证据,依靠{\ it两粒子}计算,即从任何初始度量$ f_0 $开始时,都存在一个全球弱的解决方案,以解决$ 2 $二维的抛物性矛盾的keller-segel方程。
We give a simple proof, relying on a {\it two-particles} moment computation, that there exists a global weak solution to the $2$-dimensional parabolic-elliptic Keller-Segel equation when starting from any initial measure $f_0$ such that $f_0(\mathbb{R}^2)< 8 π$.
