comment Surfaces (with boundary) in $\mathbb{R}^3$ conformal to the cylinder
What is your definition of a surface conformal to the given? Locally, globally, with respect to the ambient transformation? E.g. all surfaces intrinsically will be locally conformally equivalent. On the other hand, all ambient conformal transformations (i.e. of $\mathbb{R}^3$) will be compositions of translations, dilations and inversions.

I don't have time to write an answer now, but you can find a fairly complete one in this note. This MO question has a nice answer too.

How do you see the plane $\sigma_{i j}$ as a submanifold here?
