Mazur's uniform Mordell–Lang conjecture for curves

Let FF be a field of characteristic 00, and let CC be a smooth curve over FF, meaning a geometrically irreducible, smooth, projective curve. Write Jac(C)\operatorname{Jac}(C) for its Jacobian. For a point P0C(F)P_0\in C(F), view CP0C-P_0 as a curve in Jac(C)\operatorname{Jac}(C) via the Abel–Jacobi map based at P0P_0.

Mazur's uniform Mordell–Lang conjecture. Let g2g\ge 2 be an integer. Then there exists a constant c(g)1c(g)\ge 1 such that, for every smooth curve CC of genus gg defined over FF, every P0C(F)P_0\in C(F), and every subgroup ΓJac(C)(F)\Gamma\subseteq\operatorname{Jac}(C)(F) of finite rank rk(Γ)\operatorname{rk}(\Gamma),

#((C(F)P0)Γ)c(g)1+rk(Γ).\#\bigl((C(F)-P_0)\cap\Gamma\bigr)\le c(g)^{1+\operatorname{rk}(\Gamma)}.

This is a uniform form of the Mordell–Lang conjecture for curves, asserting a bound depending only on the genus and the rank of the subgroup. The paper identifies it as a question posed by Mazur and explains that the relative Bogomolov conjecture implies it, but the supplied text does not establish the conjecture independently or give a resolution status.
