comment A sufficient condition for a probability measure to have compact support
Yes, it does ! By any chance do you know if there is a similar characterization involving $C_\mu$ ?

comment What does the $q$-Catalan Numbers count?
I'm not sure the $q$-Catalan numbers "count things", since they are not integers

comment Notation for a functional L2 matrix norm
Well, for finite dimensional spaces, like $2\times 2$ matrices, all norms are equivalent. Thus, chose your favorite norm on $2\times 2$ matrices (I'd chose the $\sup$ over the coefficients), and then take the $L^2$ norm (with respect to $z$) of it. That's what I'll use for $\|v\|_{L^2(\Sigma)}$.

comment What is a Gaussian measure?
Hi Tom. At least for a real Banach space $X$, one may define a Gaussian measure $\gamma$ on $X$ by duality, that is a measure such that for any $f\in X^*$, $f_*\gamma$ is a (real) Gaussian measure. Maybe it does not help to much, but my point is that, for me, this is more about duality than projections. (see e.g. en.wikipedia.org/wiki/Abstract_Wiener_space)
