Generalized relative Manin–Mumford conjecture

From papers

Let π:AS\pi:A\rightarrow S be an Abelian scheme over an irreducible complex variety SS, and let YAY\subset A be irreducible and dominate SS. Let YtorrY_{\mathrm{tor}}^{\geq r} denote the set of irreducible components of YtorY_{\mathrm{tor}} of dimension at least rr. Suppose that

r+dimA>dimY+dimS.r+\dim A > \dim Y+\dim S.

If YtorrY_{\mathrm{tor}}^{\geq r} is Zariski dense in YY, then YY is contained in a proper torsion coset.

Generalized relative Manin–Mumford conjecture. Under these hypotheses, YY is contained in a proper torsion coset.

This is presented as a generalized version of the Relative Manin–Mumford conjecture, with the case r=0r=0 identified with that conjecture. The source does not specify a resolution status for the generalized statement.
