When referencing a theorem environment, you get an output consisting of just the number of the theorem. What I need is a theorem that, when referenced, displays the letter "T" next to the number (I'm using "T" as an example but I might want to use something else). Example:
Theorem 1. In a Hausdorff space, every compact subspace is closed.
T1 is important since, among other things, it's a crucial step on the proof that every continuous bijection from a compact to a Hausdorff is a homeomorphism.
Here, T1 is the reference to Theorem 1.
How could I achieve this result?
