Infinite time bubbling for the $SU(2)$ Yang-Mills heat flow on ${\mathbb{R}}^4$

Yannick Sire, Juncheng Wei, Youquan Zheng

We investigate the long time behaviour of the Yang-Mills heat flow on the bundle ${\mathbb{R}}^4\times SU(2)$. Waldron \cite{Waldron2019} proved global existence and smoothness of th…
