3. Other Geometric Flows

Problem 3.1.
[B. Kotschwar, J. Streets] Must two YangMills selfshrinkers that are asymptotic to the conical connection be actually identical? 
Problem 3.2.
[L. Ni]
More generally, if $u$ satisfies $$u^{\frac{1}{\alpha}} \det (D^2u+ug_{ij})=1,$$ for $\alpha > \frac{1}{n+2}$, can one show that $u \equiv 1$?
The case $\alpha =\frac 1 n $ is known to be true. The case $n=1$ or $n=2$ with $\alpha \in (\frac 1 2, 1)$ is also true. Form the point of view of geometry, $u$ is the Gauss curvature. 
Problem 3.3.
[J. Streets] Let $S^2$ be the 2 dimension unit sphere and $g$ be a metric on $S^2$ with positive Gauss curvature. Take $g=e^{2u} ds^2$. Consider the flow $$\partial_t u=1+\frac{\overline{K_u}}{K_u}$$ where $\overline{K_u}$ is the average of $K_u$. Known: long time existence; some weak convergence (a priori estimate degenerate at $t=\infty$).
Question: Does the flow converge to round? (If the genus is greater than 1, the analogous flow is understood). What about higher dimensions? More information for $n=2$ can be found on the paper on arxiv.
