Genus and Gonality of Small Curves, Dynamical Uniform Boundedness, and Bifurcation

Zhuchao Ji, Junyi Xie

The paper proves that the gonality of dynatomic curves in non‑isotrivial families of rational maps on the projective line grows without bound, and uses this to obtain uniform bound…

Space spanned by characteristic exponents

Zhuchao Ji, Junyi Xie, Geng-Rui Zhang

We prove several rigidity results on multiplier spectrum and length spectrum. For example, we show that for every non-exceptional rational map $f:\mathbb{P}^1(\mathbb{C})\to\mathbb…

Rigidity of Lyapunov exponents for polynomials

Zhuchao Ji, Junyi Xie, Geng-Rui Zhang

Let be polynomials of degree with disconnected Julia sets. We prove that they have the same Lyapunov exponent $\mathcal{L}_f=\mathcal{L}_g…

Equidistribution speed of iterated preimages for rational maps on the Riemann sphere

Mai Hao, Zhuchao Ji

The exponential equidistribution speed of iterated preimages for holomorphic endomorphisms on was established by Drasin-Okuyama for , and by Dinh-Sibony for arb…

A geometric approach to the uniform boundedness of -primary torsion points

Zhuchao Ji, Jiarui Song, Junyi Xie

We prove that for a non-isotrivial abelian scheme over a smooth curve, the genus of a generic sequence of multi-sections with small heights tends to infinity. As an application, we…

Cyclotomic integral points for affine dynamics

Zhuchao Ji, Junyi Xie, Geng-Rui Zhang

Let be a regular endomorphism of algebraic degree (i.e., extends to an endomorphism on of algebraic degree ) defined…
