The number of quartic $D_{4}$ -fields with monogenic cubic resolvent ordered by conductor

Cindy Tsang, Stanley Yao Xiao

In this paper, we consider maximal and irreducible quartic orders which arise from integral binary quartic forms, via the construction of Birch and Merriman, and whose field of fra…

On the self-duality of rings of integers in tame and abelian extensions

Cindy Tsang

Let $L / K$ be a tame and Galois extension of number fields with group $G$ . It is well-known that any ambiguous ideal in $L$ is locally free over $O_{K} G$ (of rank one), and…

Binary quartic forms with bounded invariants and small Galois groups

Cindy Tsang, Stanley Yao Xiao

In this paper, we consider integral and irreducible binary quartic forms whose Galois group is isomorphic to a subgroup of the dihedral group of order eight. We first show that the…
