Jun 7 comment the following inequality is true，but I can't prove it Have you tried the Abel transform en.wikipedia.org/wiki/Summation_by_parts ? Jun 4 comment What is characteristic function of maximum of i.i.d. random variables? But $P(\max(X_1,X_2) \le t)= P(\{X_1 \le t\} \cup \{X_2 \le t\}).$ May 29 comment Do there exist transcendental numbers which are not hypertranscendental? The question was asked at XI St.Petersburg Summer Meeting in Mathematical Analysis in 2002, but not answered there. May 29 accepted Do there exist transcendental numbers which are not hypertranscendental? May 29 comment Do there exist transcendental numbers which are not hypertranscendental? @Lucas Culler: Could you explain in detail why $g(t)$ and $g(t)h(t)$ have rational coefficients? As far as I understand it, $z$ is not necessarily rational.
