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…

Class fields generated by coordinates of elliptic curves

Ho Yun Jung, Ja Kyung Koo, Dong Hwa Shin

Let $K$ be an imaginary quadratic field different from $Q (- 1)$ and $Q (- 3)$ . For a nontrivial integral ideal $m$ of $K$ , let $K_\mathfrak{…

On some $p$ -adic Galois representations and form class groups

Ho Yun Jung, Ja Kyung Koo, Dong Hwa Shin +1

Let $K$ be an imaginary quadratic field of discriminant $d_{K}$ with ring of integers $O_{K}$ . When $K$ is different from $Q (- 1)$ and $Q (- 3)$ ,…

Form class groups and class fields of CM-fields

Ho Yun Jung, Ja Kyung Koo, Dong Hwa Shin +1

Let $F$ be a totally real number field of class number one, and let $K$ be a CM-field with $F$ as its maximal real subfield. For each positive integer $N$ , we construct a class gro…
