An Infinite Family of Real Quadratic Fields with Three Classes of Perfect Unary Forms

Christian Porter

In this paper, we revisit the theory of perfect unary forms over real quadratic fields. Specifically, we deduce an infinite family of real quadratic fields w…

Unit Reducible Cyclotomic Fields

Christian Porter, Piero Sarti, Cong Ling +1

In this paper, we continue the study of unit reducible fields as introduced in \cite{LPL23} for the special case of cyclotomic fields. Specifically, we deduce that the cyclotomic f…

Strongly Reduced Lattice Bases

Christian Porter

In this paper, we show that for each lattice basis, there exists an equivalent basis which we describe as ``strongly reduced''. We show that bases reduced in this manner exhibit ra…

On Pisot Units and the Fundamental Domain of Galois Extensions of

Christian Porter, Alexandre Bali, Alar Leibak

In this paper, we present two main results. Let be a number field that is Galois over with degree , where is the number of real embeddings and is the…

A New Bound for the Orthogonality Defect of HKZ Reduced Lattices

Christian Porter, Edmund Dable-Heath, Cong Ling

In this work, we determine a sharp upper bound on the orthogonality defect of HKZ reduced bases up to dimension . Using this result, we determine a general upper bound for the o…

An Upper Bound on the Number of Classes of Perfect Unary Forms in Totally Real Number Fields

Christian Porter, Andrew Mendelsohn

Let be a totally real number field of degree over , with discriminant and regulator respectively. In this paper, using a similar method to van Woerde…

Unit Reducible Fields and Perfect Unary Forms

Alar Leibak, Christian Porter, Cong Ling

In this paper, we introduce the notion of unit reducibility for number fields, that is, number fields in which all positive unary forms attain their nonzero minimum at a unit. Furt…

Reduction Theory of Algebraic Modules and their Successive Minima

Christian Porter, Cong Ling

Lattices defined as modules over algebraic rings or orders have garnered interest recently, particularly in the fields of cryptography and coding theory. Whilst there exist many at…
