Abstract
We compute the class of the closure of the locus of hyperelliptic curves in the moduli space of stable genus-3 curves in terms of the tautological class and the boundary classes and . The expression of this class is known, but here we compute it directly, by means of Porteous Formula, without resorting to blowups or test curves.
