利用齐次Besov空间研究了Keller-Segel系统的Cauchy问题。利用齐次Besov空间B˙p,∞−2+np(Rn),即Keller-Segel系统的标度临界情况,在空间中获得了小初始数据的全局解。此外,还研究了Keller-Segel系统的病态性。
The Cauchy problems for Keller–Segel system are studied using homogeneous Besov spaces. With the homogeneous Besov spaces B˙p,∞−2+np(Rn), which is the scaling critical case for Keller–Segel system, global solutions for small initial data are obtained in the space. In addition, ill-posedness for Keller–Segel system is also studied.
