On the Geometry and Shapes of Rank 2 Log Unit Lattices
Jose Cruz, Erik Holmes, Fatemeh Jalalvand +3
Every number field canonically gives rise to two lattices: its ring of integers and its log unit lattice. While the shapes of the former have undergone extensive research, far less…

Unit lattices of -quartic number fields with signature
Sergio Ricardo Zapata Ceballos, Sara Chari, Erik Holmes +5
There has been a recent surge of interest on distributions of shapes of unit lattices in number fields, due to both their applications to number theory and the lack of known result…

Shapes of unit lattices in -number fields
Robert Harron, Erik Holmes, Sameera Vemulapalli
The unit group of the ring of integers of a number field, modulo torsion, is a lattice via the logarithmic Minkowski embedding. We examine the shape of this lattice, which we call…
