Symmetry in stationary and uniformly-rotating solutions of active scalar equations

In this talk, I will discuss the symmetry in uniformly rotating solutions of 2D Euler and SQG. We want to answer whether every stationary/uniformly-rotating solution must be radially symmetric, if the vorticity is compactly supported.
