You could use the "dictionary" between closed subsets of projective $n$-space and ideals of k[a_0,\ldots,a_n]$. Being irreducible as a closed subset usually boils down to the polynomials being irreducible. Feb3 suggested rejected edit on Definition of tamely ramified Feb2 comment Is the number of automorphisms of a hyperelliptic curve bounded The curve$y^2=x^{2g+1}+1$admits the automorphism$(x,y)\mapsto (\zeta_{2g+1}^n x, y)$for all$n=1,\ldots,2g+1$. Thus, the number of automorphisms of this hyperelliptic curve is at least$2g+1$. Is this correct?

Then its minimal regular model coincides with its minimal Weierstrass model.
