Suppose I can have $m=r$, so $A$ is a square matrix. Can we say anything more in this case?

C_1 = 0 C_2=1 C_3=0 C_4=3 C_5=0 C_6=15 C_7=0 C_8=105 Jun 17 comment Solving a system of polynomials in $N$ variables I am actually interested in matching the first $l$ moments of a given distribution (the $(C_p)_{p=1,...,l}$ with the moments of an equally-weighted Dirac mixture. Jun 16 comment Solving a system of polynomials in $N$ variables @VictorLiu : Almost but not quite. Note I take $(v_i)^p$ and not $|v_i|^p$ in my sums, so they are not norms.

Yes, $\alpha \mapsto Q_{\alpha}$ is continuous at all continuity points of the CDF of $\mu$ but I am interested in continuity w.r.t. the measure.

Is there any way to determine the (non-)differentiability of $F$ without actually computing $$\int_0^1 \frac{f(t,h) - f(t,0)}{h} dt$$ ? My question is coming from a real problem where I can compute derivatives of $f$ w.r.t $x$ but cannot explicitly integrate $f$ w.r.t $t$.

I don't quite see how it helps with determining smoothness in the variable $x$, though. Jun 28 awarded Promoter
