comment PDF of sum of two random variables
@wordsthatendinGRY this problem says uniform distribution on $\mathbb{S}^n$ and Gaussian random variable in $\mathbb{R}^n$.

comment To what extent is it possible to generalise a natural bijection between trees and $7$-tuples of trees, suggested by divergent series?
fr.arxiv.org/abs/math/0004133 it doesn't answer your question or come close, but maybe it's related. Also en.wikipedia.org/wiki/Combinatorial_species

@JyrkiLahtonen $p_n(x) = (x+n)^2 - n + 1$, I guess you are right.

Are you minimizing with respect to $V$ or $y$ ?

comment The Gaussian moat problem and its extension to other rings in $\mathbb{C}$, $\mathbb{H}$ and $\mathbb{O}$
@BennettGardiner I recommend you ask separately the your "Gaussian Moat" questions for the rings $\mathbb{Q}[e^{2\pi i /3}]$, $\mathbb{H}$, $\mathbb{O}$, so they can all get the attention they deserve.

comment Fourier transform - epicycles.
It might be easier in complex coordinates. Try $z(t) = e^{it} + a e^{3it}$ for a small number $a << 1$. You have to separate the real and imaginary parts.
