comment Curvature of a level set
If you want straight lines to be your answer, shouldn't you penalize for the sum of the absolute value of curvature of all points?

comment Question about the definition of convergence in measure.
The first equality in the second long equation, you are interchanging two limits. This is not always true.

comment Are convex functions enough to determine a measure?
@ByronSchmuland Thanks! It's a nice argument. Please change the very last measure to $\nu(dx)$. I will then accept your answer. Thanks a lot!

comment Are convex functions enough to determine a measure?
@ByronSchmuland I am sorry, but is that function still convex? For example, the function $f(x,y)=xy$ should not be convex.

@ByronSchmuland, what is the analogous functions for $f$ and $g$ in higher dimensions?

So it does work if the measures are compactly supported.

comment Are convex functions enough to determine a measure?
didn't realize compact domain would make such a huge difference. Thank you. For your last remark, suppose we are dealing with measures that have compact support, how may one prove convex functions are enough? I suppose it would require some approximation of continuous functions by convex functions that I am not aware of.

comment Is the boundedness necessary to extend harmonically?
Why are the conditions different between harmonic functions and holomorphic function?
