comment Dimensional reduction of system of ODEs
What do you mean by "identical to"? The long-term behaviour is all $X_i \to 0$. Presumably you want to say something more interesting about it.

Are these supposed to be autonomous differential equations?

comment Positive Integers Equation
Slightly more interesting would be $x + y^4 = LCM(x,y)$. Still no solutions though.

The series converges for $|x|<1/e$, as has already been noted.

By "generalized hypergeometric function" do you mean a ${}_pF_q$ function or something else? There are many possible generalizations.

comment Dividing the square
Part of the art of interviewing is to clarify, by asking appropriate questions, exactly what the interviewer means by a question such as this.

Actually converges for $|x| < 1/e$ (use Stirling's approximation).

comment Examples of mathematicians getting started on a PhD 'late' in life.
@JoonasIlmavirta According to the Fields medal rules, that would pretty much require getting the Fields medal before the PhD.
