(This is my personal view. Don't take it personally.)
Nowdays, it's very difficult for new users to post a question, new user get downvoted/closed by the CURED group.
I think we should not downvote the new user's question, we should give them more chances to post more questions.
I agree t...
In this post, the user @ mentioned a user and that became a link to his user ID. Usually, when we do this, it is not the case.
Is it a new feature?

I was asked to find 50th percentile $\xi_Z^{0.5}$ for random variable $Z = \exp(-0.05T)$ where $T$ has half-normal distribution, with p.d.f. of the form $\frac{2}{10\sqrt{2\pi}} e^{-t^2/200}$, where $t>0$.
From definitions we have $0.5 = P(Z\leq \xi_Z^{0.5})$, and if we plug in $\exp(-0.05\xi_T^{...
In probability theory and statistics, the half-normal distribution is a special case of the folded normal distribution.
Let

Let $K$ be a number field and $v$ be it's non-archimedian valuation.
Then, I would like to prove $K_v(a^{1/m}) /K_v$ is unramified if
only if $v(a)≡0 \pmod m$.
I know unratified extension of local field is in bijection with extensions of the residue field. Thus, the unramified extension is ge...
