Let $X$ be a smooth projective variety over $k$ and $G$ a finite group acting on $X$. Furthermore $\mathrm{char}(k)$ does not divide the order of $G$. Consider the quotient stack $[X/G]$. Is it right that this is a smooth, proper and connected DM stack with coarse moduli space. I mean this should be true since $X\rightarrow[X/G]$ is the cover and $X//G$ the moduli space right?

  • $\begingroup$ I think you mean "... DM stack with coarse moduli space $X//G$." Yes, this is correct. $\endgroup$
