p-adic Rigidity and Supercongruences at Rank Two Attractors
Yu Fu
We study a -adic rigidity phenomenon suggested by rank two attractors. Near an ordinary special fiber of a Calabi--Yau family, the excellent Frobenius of Beukers and Vlasenko ac…

Families of isogenous elliptic curves ordered by height
Yu Fu
Given a family of products of elliptic curves over a rational curve defined over a number field , and assuming that there exists no isogeny between the pair of elliptic curves i…

Abelian varieties with real multiplication: classification and isogeny classes over finite fields
Tejasi Bhatnagar, Yu Fu
In this paper, we provide a classification of certain points on Hilbert modular varieties over finite fields under a mild assumption on Newton polygon. Furthermore, we use this cha…
