On the integrality of modular functions over $Z [j]$ and Kronecker-type congruences

Ho Yun Jung, Ja Kyung Koo, Dong Hwa Shin

Let $N$ be a positive integer and let $f$ be a meromorphic modular function of level $N$ with rational Fourier coefficients. For a prime $p$ , define a function $f_{p}$ on the complex…

Inverse limits of CM points on certain Shimura varieties

Ho Yun Jung, Ja Kyung Koo, Dong Hwa Shin

Let $N$ be a positive integer, and let $D \equiv 0$ or $1\Mod{4}$ be a negative integer. We define the sets $CM (D, Y_{1} (N)^{\pm})$ and $CM (D, Y (N)^{\pm})$ as subsets…

The volumes of the Hitchin-Riemann moduli spaces are infinite

Suhyoung Choi, Hongtaek Jung

In this study, we prove that the actions of the mapping class groups on a large range of higher TeichmÃ¼ller spaces with a rank of at least two possess infinite Atiyah-Bott-Goldman…
