My question is the following: if I know $f''(x)<0,~\forall~0\leq x\leq a$ and I know that $f'(c)=0$ where $c\in[0,a]$ and I also know $f(0)=0$, then is that true $f(x)>0,~\forall~x\in(0,c]$?
I think it is correct.
Hello,
This is a soft question. How do people usually use arxiv to put their papers? At which stage does one usually put his/her paper/report there? Someone suggests me to submit a paper while putting it on arxiv. Is that the convention that people follow?
Thank you!

@MartinSleziak I waited a bit to see whether I get some feedback here. No response so far - I have added both tags I've mentioned; we will see whether somebody corrects them. (If some of the tags is not a good fit, that is.)
