Degree Growth of Iterates of Curves and Likely Intersections

Sina Saleh, Jit Wu Yap

We study the growth of the bidegree of an ample irreducible curve in $P^{1} \times P^{1}$ under a product polynomial endomorphism $φ = (f, g)$ , where at least one of $f$ …

Finiteness of an Isogeny Class via Equidistribution

Jit Wu Yap

In a very recent, beautiful paper, Junyi Xie and Ziquan Yang gave a new proof of Faltings' isogeny theorem over number fields by reducing to Tate's theorem over finite fields. We s…

Non-Archimedean Rigidity and Uniformity for Common Preperiodic Points

Chen Gong, Jit Wu Yap

Let $k$ be an algebraically closed, complete non-Archimedean field of residue characteristic $0$ . Let $f$ be a polynomial of degree at least $2$ over $k$ which does not have potent…

Uniform boundedness of small points on abelian varieties over function fields

Nicole Looper, Jit Wu Yap

Let $k$ be a field of characteristic $0$ and let $K = k (B)$ be the function field of a geometrically irreducible projective curve $B$ over $k$ . Let $A / K$ be a $g$ -dimensional abeli…

On the pointwise convergence of the number of abelian varieties over $F_{p}$ with fixed trace

Zhao Yu Ma, Jit Wu Yap, Jeff Achter +1

Extending Katz-Sarnak heuristics, Ballini-Lombardo-Verzobio [BLV25] conjectures a limiting distribution as $p \to \infty$ for $# A_{g} (F_{p}, t)$ , the number of $g$ -dimensional…
