TLDR
In this paper, the authors showed that the set of all stable curves X over O_K with (K_{X/S})^2 / [K : Q] > heightFal(J(X_K)), where X is the canonically metrized dualizing sheaf of X over S = Spec(O_K) and heightFal is the Faltings modular height of the Jacobian of X_K, is finite under the following equivalence.
Abstract
Let K be a number field, O_K the ring of integers of K and X a stable curve over O_K of genus g >= 2. In this note, we will prove a strict inequality ( (K_{X/S})^2 / [K : Q] ) > Height_{Fal}(J(X_K)), where $K_{X/S}$ is the canonically metrized dualizing sheaf of X over S = Spec(O_K) and Height_{Fal}(J(X_K)) is the Faltings modular height of the Jacobian of X_K. As corollary, for any constant A, the set of all stable curves X over O_K with ( (K_{X/S})^2 / [K : Q] ) <= A is finite under the following equivalence. For stable curves X and Y, X is equivalent to Y if X is isomorphic to Y over O_{K'} for some finite extension field K' of K.

- 01 Nov 1996 - 
TL;DR: In this article, a sharp slope inequality for general stable fibrations has been shown for stable curves with at most one node of type i>0. But this inequality is not applicable to stable curves of genus g ≥ 2.

Inequalities for semistable families of arithmetic varieties

TL;DR: In this paper, a generalization of Bogomolov's inequality and Cornalba-Harris-Bost's inequality to the case of semistable families of arithmetic varieties under the idea that geometric semistability implies a certain kind of arithmetic positivity was proposed.
