Q: Correlation Between Two Skellam-Distributed Random Variables

BrianI have two Skellam-distributed random variables, $X_1$ and $X_2$, with rate parameters $\mu_{1,+}, \mu_{1,-}$ and $\mu_{2,+}, \mu_{2,-}$ respectively. (For my case, it just so happens that their distributions are symmetric, i.e. $\mu_{1,+} = \mu_{1,-}$ and $\mu_{2,+} = \mu_{2,-}$.) Now I want t...

The Skellam distribution is the discrete probability distribution of the difference N 1 − N 2 {\displaystyle N_{1}-N_{2}} of two statistically independent random variables N 1 {\displaystyle N_{1}} and N 2 , {\displaystyle N_{2},} each...

What's the difference of usage between and ?
 
@Andrews Vector-analysis, according to the tag wiki, are for "Questions related to understanding line integrals, vector fields, surface integrals, the theorems of Gauss, Green and Stokes". So it is about multi-variable calculus (To me "vector-calculus", which is a synonyms, is a more common terms).

Q: How do I demonstrate Jordan measurability of a compact convex polytope?

JHH2020Ex 1.1.9 in Tao's An introduction to measure theory asks us to show that any compact convex polytope in $\mathbb{R}^d$ is Jordan measurable. Is the following an efficient (or even valid) approach to the problem? Show that every $d$-dimensional solid simplex is Jordan measurable; and Show that a...

Q: Well definedness of Lebesgue inner measure

bringingdownthegaussThis is for homework: if $A,A'$ are two elementary sets containing $E$, bounded set in $\mathbf{R}^d$, then $m(A)-m^*(A \backslash E)$ is equal to $m(A')-m^*(A \backslash E)$ So far my goal has been to show that they're both equal to the expression for $A \cap A'$ which is another elementary set...

Was there some general discussion on Mathematics Meta concerning tag a specific mathematician?
I remember somewhat related discussion on MathOverflow Meta: Should we create an Erdős tag? (However, many things on the two sites are different.)
