Recently created tag. Useful? Too specific? BTW the question where it was created also misses top-level-tag.
3  Let $X$ be the set of functions $e^{p(x)}$ of the real vector $x$, where $p$ is a multivariate polynomial with $p(0)=0$. Is any finite subset of $X$ linearly independent? If yes, why? If no, is the answer true for other, restricted choices of $p$? (The answer is yes when the polynomials are re...

Another tag listed among new tags is . On math.SE, there is tag called means - the usage is somewhat unclear but at least to some extent it is used quite reasonably.
3  Let me given with an obvious example. Let $\Omega\subset{\mathbb R}^n$ be an open domain. If $f,g\in L^1(\Omega)$ and $f,g\ge0$, then $\sqrt{fg}\,\in L^1(\Omega)$. Now let me replace the absolutely continuous measures $f(x)dx$ and $g(x)dx$, by a pair $\lambda,\mu$ of non-negative bounded measure...

1  For integers $n\geq 1$ with $$\operatorname{rad}(n)=\prod_{\substack{p\mid n\\p\text{ prime}}}p$$ we denote the squarefree kernel or radical of an integer $n$ (see if you want this Wikipedia). And $\varphi(n)$ denotes the Euler's totient funciton. Then while I was stuying the equation \operator...

0  User @EvgenyKuznetsov has recently edited a lot of years-old posts in which, as far as I can tell, he is just TeXifying titles. While I assume that this is being done with good intentions, it seems likely that he does not realise that he is bumping these, in many cases long-dormant, posts to the...

@EvgenyKuznetsov This post is related to your recent edits, so I thought it might be good to make you aware of it: Repeated TeXifying of question titles. And there are also some other posts on meta related to this, such as Do we have an unofficial quota on how many old questions one should bump for minor edits in a single day? or Editing titles to include $\mathfrak{LaTeX \; Math}$. (Maybe you have noticed also some feedback if you looked at reviews of your suggested edits.) — Martin Sleziak 1 min ago
I assume you are aware that simply writing @username in a post does not notify the user. I have pinged the user you mentioned to make him aware of your post on meta. — Martin Sleziak 16 secs ago
