The effective geometric Bogomolov conjecture for curves

About 14 years old · traced to

Let CC be a smooth projective curve over K‾\overline{K} of genus at least 22, let JCJ_C be its Jacobian, let DD be a degree-one divisor, let jD:C→JCj_D:C\to J_C be the associated embedding, and let ∥⋅∥NT\lVert\cdot\rVert_{\mathrm{NT}} be the canonical Néron–Tate seminorm. Call CC isotrivial if it is obtained by base change from a curve over the constant field. Effective geometric Bogomolov conjecture for curves. If CC is non-isotrivial, then there exists ϵ>0\epsilon>0 such that

{x∈C(K‾)∣∥jD(x)−P∥NT≤ϵ}\{x\in C(\overline{K})\mid\lVert j_D(x)-P\rVert_{\mathrm{NT}}\leq\epsilon\}

is finite for every P∈JC(K‾)P\in J_C(\overline{K}). Moreover, if CC has a stable model over B\mathfrak{B}, such an ϵ\epsilon should be describable effectively in terms of geometric information from that stable model. This is explicitly stated as a stronger, effective form of the curve conjecture; its effectivity assertion remains open.
