We prove that the positive-dimensional part of the torsion locus of the Ceresa normal function in *\mathcal{M}_g* is not Zariski dense when *g\geq 3*. Moreover, it has only finitely many components with generic Mumford-Tate group equal to *\mathrm{GSp}_{2g}*; these components are defined over *\overline{\mathbb{Q}}*, and their union is closed under...
