Ray class fields generated by torsion points of certain elliptic curves
Ja Kyung Koo, Dong Hwa Shin, Dong Sung Yoon
We first normalize the derivative Weierstrass -function appearing in Weierstrass equations which give rise to analytic parametrizations of elliptic curves by the Dedekind …

Normal bases of ray class fields over imaginary quadratic fields
Ho Yung Jung, Ja Kyung Koo, Dong Hwa Shin
We develop a criterion for a normal basis, and prove that the singular values of certain Siegel functions form normal bases of ray class fields over imaginary quadratic fields othe…

Projective Deformations of Hyperbolic Coxeter 3-Orbifolds
Suhyoung Choi, Craig D. Hodgson, Gye-Seon Lee
By using Klein's model for hyperbolic geometry, hyperbolic structures on orbifolds or manifolds provide examples of real projective structures. By Andreev's theorem, many 3-dimensi…
