I keep coming across results of the form: If we take the quotient of the upper half plane by a Fuchsian group with this property, we get a surface with that property (cusps, funnels, in/finite area, ...).
Could you recommend a reference for those kinds of results?
Here are a few references to get you started:
Thurston's notes and the book form, Geometry and Topology of 3-Manifolds
Introduction to Teichmuller Theory, by Hubbard
Lectures on Hyperbolic Geometry, by Benedetti and Petronio
