The following question is related to this previous question, Canonical immersion of the double torus:

Is there any known explicit (maybe algebraic) isometric embedding of a genus 2 surface endowed with a metric of constant curvature K = -1 into a Hilbert space of finite dimension?

  • $\begingroup$ Or, to be more concrete, into $\mathbb{R}^n$ for some $n > 0$? $\endgroup$

  • $\begingroup$ I’m pretty sure none is known, and it’s an open question whether any such “explicit” embedding or evening just immersion exists. $\endgroup$
