To avoid complications, assume that $F$ is irreducible and remains so over $\bar{k}$ (the algebraic closure of $k$). A point $a=(a_{1},\ldots,a_{n})\in\bar{k}^{n}$ on $H$ is singular if $(\partial F/\partial X_{i})(a)=0$ for $i=1,\ldots,n$. The hypersurface $H$ is smooth if it has no singular points with coordinates in $\bar{k}$. | |
