comment Automorphism group of a lattice's Voronoi cell
It's hard to say since finite subgroups of $O(n)$ can be quite varied. en.wikipedia.org/wiki/Crystallographic_restriction_theorem

comment the measurability of $\int_0^t X(s)ds$
Filtration here means $s< t$ implies $\mathcal{F}_s \subset \mathcal{F}_t$. Adapted means $X(t)$ is $\mathcal{F}_t$-measurable. I am trying to think of adapted processes that are not simple...

comment asymptotic expansion for Bessel function $I_0(z)$ in terms of Gauss hypergeometric functions ${}_2F_1$
@Qmechanic don't mind me. Peter showed me his paper in the summer. I have been treating it as a crash course in special functions.
