comment Canonical term for $\overline X / X$ where $X$ is a normed space.
This appears in the theory of Hilbert complexes, as quotient of the closure of the boundaries by the boundaries. More, generally, for Banach complexes see: link.springer.com/article/10.1007%2FBF02922133?LI=true

comment Formula for surface measure of spherical cap on $S^n$.
In the section 'hyperspherical cap', the wikipedia article gives a formula for the surface in terms of regularized incomplete beta functions. I wonder whether a single integral formula like for the volume, at the beginning of the same section, does exist.

I am specifically looking for formulas nicer than there.
