On some arithmetic properties of Siegel functions (II)

Ho Yun Jung, Ja Kyung Koo, Dong Hwa Shin

Let $K$ be an imaginary quadratic field with discriminant $d_{K} \leq - 7$ . We deal with problems of constructing normal bases between abelian extensions of $K$ by making use of singula…

Ray class invariants over imaginary quadratic fields

Ho Yun Jung, Ja Kyung Koo, Dong Hwa Shin

Let $K$ be an imaginary quadratic field of discriminant less than or equal to -7 and $K_{(N)}$ be its ray class field modulo $N$ for an integer $N$ greater than 1. We prove that si…

Ring class invariants over imaginary quadratic fields

Ick Sun Eum, Ja Kyung Koo, Dong Hwa Shin

We show by adopting Schertz's argument with the Siegel-Ramachandra invariant that singular values of certain quotients of the $Δ$ -function generate ring class fields over imaginary…
