comment What does the notation $f(x-0) $ or $f(x+0)$ mean?
Thanks @D.Clark, that is what I thought. Can you have a look at the second example I've put up please.

Thank you. I think that is fine.

Thanks, I was hoping not to lose the $\gamma$ though, do you know if there's a way.

comment Two definitions of $H^1(\partial\Omega)$, one using charts and one use tangential gradients
@Quickbeam2k1 sadly that book is not here in my library (so I can't attempt to decipher the German). I will take alook at Laplace-Beltrami..

comment What does “flat hypersurface” mean?
Thanks. I am not familiar with curvature much. In $\mathbb{R}^2$, is a flat hypersurface with boundary then say a line segment? In $\mathbb{R}^3$ it is part a segment of a plane?
