Nov 19, 2013 at 15:10 comment added Vamsi Yes x is the norm of the Teichmuller map. Sorry, I am a novice in this field. So you are saying that if the $L^{\infty}$ norms of some Beltramis get close to the extremal $L^{\infty}$, then the corresponding q.c maps get close in the uniform topology (also I don't want just a subsequence but the entire sequence to converge)? If so, can you cite a reference. Thanks a million!
Nov 19, 2013 at 5:52 comment added Misha Do you assume in the 2nd paragraph that $x$ is the norm of the Teichmuller map $g$ (equal to $f$ from the 1st paragraph)? Otherwise, the answer is clearly negative. If $g$ is indeed extremal, then the answer is obviously positive because of the convergence property for qc maps; convergence is uniform on the 2-sphere.
