Abstract

We consider the SO(d)SO(d)-equivariant Yang-Mills heat flow \begin{equation*} \partial_t u-\partial_r^2 u-\frac{(d-3)}{r}\partial_r u+\frac{(d-2)}{r^2}u(1-u)(2-u)=0 \end{equation*} in dimensions d>10.d>10. We construct a family of C\mathcal{C}^{\infty} solutions which blow up in finite time via concentration of a universal profile \begin{equation*} u(t,r)\sim Q\left(\frac{r}{\lambda(t)}\right), \end{equation*}where QQ is a stationary state of the equation and the blow-up rates are quantized by \begin{equation*} \lambda(t)\sim c_{u}(T-t)^{\frac{l}{\gamma}},\,\,\,l\,\,\,\text{is any positive integer},\,\,\,\gamma=\gamma(d)=\frac{d-4-\sqrt{(d-6)^2-12}}{2}. \end{equation*} Moreover, such solutions are in fact (l1)(l-1)-codimension stable under pertubation of the initial data.
