I am currently an undergraduate maths student at Cambridge University, England.

I aim to answer what questions I can, understand some of those that I can't and improve the site however I can!

@PeterFranek I believe the last condition is a typo, and should be $y = (0,t)$, you need this to make the relation symmetric.

comment Preimages of smooth maps between manifolds
@TedShifrin Yes, which is assumed in the question.

Yes, $Im(f)$ having nonzero measure works fine since then it must contain a regular point by Sard's theorem, the preimage of which will be a nonempty, finite set of points.
