“…Nevertheless, it is always trivial for hyperelliptic curves, and it has long been conjectured that these are the only curves with trivial Ceresa cycle [13,Question 8.5], [4,Remark 1.2]. Although several recent results [1,2,4,14] present nonhyperelliptic curves whose Ceresa cycles give rise to torsion classes in the Griffiths group, this problem remains open. The goal of this paper is to study hyperellipticity of tropical curves and graphs using cohomological invariants arising from the study of Ceresa triviality of algebraic curves defined over C((𝑡)).…”
