comment Snake-like continua and universal images
The concepts of span and semispan - which are classical and well established, though admittedly somewhat specialised - can be found in the references provided. I think for an answer, as opposed to a question, that should be sufficient, but I will add some details when I get the chance.

comment explicit conformal map of sinus-shaped region
Explicit conformal maps can almost never be given; why would you expect one here? The answer is highly likely to be "no", but good estimates can be given about the behaviour of the conformal map if required.

comment End points of continua
As mentioned in my answer, the definitions do not coincide even in the case of arc-like (=chainable) continua; consider the $\sin(1/x)$-continuum.

comment Can you write $\mathbb R^2$ as a disjoint union of two totally disconnected sets?
It's nice to use Borsuk's theorem. Of course, you can also use Janiczewski's theorem, which is perhaps more elementary (see also my new answer to the question referenced by Kristal).

comment Can you write $\mathbb R^2$ as a disjoint union of two totally disconnected sets?
But actually, as noted in the question there, the result (any disconnected subset of the plane can be disconnected by a closed connected set) does not require any assumption of closedness / compactness. (See also the answer I just gave there.) So this does in fact answer the question.

What is the problem with taking $z_n=2\pi n i$ and $p(x,y) = y-1$?

comment Estimates for hyperbolic metrics on nested surfaces
@AdamEpstein I agree that it's not at all clear how one would search for this in the literature, as it is most likely to appear somewhere as an auxiliary result (as it does in our paper, and your thesis). So hopefully someone might remember having seen this in the classical literature.
