Thank you for explaining. Jan29 comment Zero variance Random variables with density @jameselmore : If $X$ is a r.v. with density $f$, then $p(X=m)=\int_m^m f(t) dt=0$. Is'nt true ? Jan29 asked Zero variance Random variables with density Dec29 comment About a limit with Euler $\Gamma$ function. it's awesome work Felix! Thank you! Dec29 accepted About a limit with Euler $\Gamma$ function. Dec29 comment About a limit with Euler $\Gamma$ function. @Mhenni: There is my solution about the limit of $G$ :Let use put: $F(x)=\int_x^{+\infty} t^{x-1} e^{-t} dt$ and: $u=\frac{t}{x}.$ That gives : $F(x)= x^x \int_1^{+\infty}u^{x-1}e^{-ux} du$. If $x > 1$ then: $F(x) \geq x^x \int_1^{+\infty}e^{-ux} du =x^{x-1}e^{-x} \to +\infty$ when $x \to +\infty$.
