Rellich Embedding Theorem for the $2$-Sphere
Ah! Proposition 2.4 of books.google.co.uk/… uses the kind of local charts needed here (the second sentence of the proof).

Rellich Embedding Theorem for the $2$-Sphere
Re. relevance of extra structures: I don't think the Kahler structure really gives you any extra useful information.

Projection of a function $f\in L^1(\Omega)$ onto a finite dimensional subspace
Are you primarily interested in an answer for a specific choice of $g_1,\dots,g_k$, or in full generality? I guess you'd have said if it was the former, but no harm in asking!

Why is this test function admissible? [Paper explanation]
"Thus $\psi(u_n(t))\chi_{(0,t)}$is basically the function we use to integrate against $P(u_n), f_n$ and for that reason the wide term "test function" is adopted." - that is my understanding yes.

Substitute Concrete Value in Conditional Expectation
@IosifPinelis: I don't disagree with anything you've written, it just seemed to me that the OP was asking a slightly different question. It seems not given that the OP has accepted your answer :)

Substitute Concrete Value in Conditional Expectation
I was going to use the word distribution instead of `functional' there for a second...

Substitute Concrete Value in Conditional Expectation
I read this question as being about the functional $\mu_{X,Y,f}:\psi\longmapsto \int\int\psi(y)f(x,y)(dP^{X,Y}(x,y) - dP^X(x)dP^Y(y))$ for a fixed choice of $f$.

Substitute Concrete Value in Conditional Expectation
What happens $P_X$ and $P_Y$ supported on finite (or compact) sets and let $f(x,y)=1$?

*probability, not 'probabilit'...

Substitute Concrete Value in Conditional Expectation
The notion of a regular conditional probabilit (sometimes called a transition kernel) is usually helpful with this sort of thing. Do you have a particular set of circumstances where you'd like your $\varphi$ to exist?
