I am a master student in mathematics who writes his master thesis (Determinantal Point Processes) - or tries to if he doesn't spend too much time on mathematics which isn't part of his thesis.

comment The value of $\lim_{x\to +\infty} \dfrac{e^{x^2}}{10^{|x|}}$
You probably mean $k=\ln(10)$...

comment Conditional Expectation of a Poisson Random Variable
The probability of "X" and "X is odd" is the same as "X is odd". ($P(\{X \in \mathbb{N}\}\cap\{X \text{ is odd}\})=P(\Omega\cap\{X \text{ is odd}\})=P(\{X \text{ is odd}\})$). Then A is not a random variable but a set - and random variables are not events...

comment Riemann's Integrals Question
When I look at this (and the answer using the FToC) - and especially the result - I asked myself if one could compare this series to the alternating harmonic series. For example bound it from above or below by the alternating series. I don't know if this could work, but it would seem interesting. At least the way using the FToC is far more efficient and usable.

comment Trying to prove “If the expectation of the random variable is a measure, then the random variable is a random measure.”
@MattN. Oh I forgot the obvious pigeons. Just let me get one from my shack on the roof... I meant of course on this site, but nevermind. Electronic mails are quite useful...

@MattN. Ah, ok then let me offer the bounty - if it is still possible. (By the way: How could I communicate with you by not using these comments?)

Ah, I see. It was just too nice a statement to be true in that generality (i.e. when X was of an arbitrary form...) Thanks a lot for the effort!
