The equidistribution of lattice shapes of rings of integers of cubic, quartic, and quintic number fields: An artist's rendering.

摘要

A fascinating tale of mayhem, mystery, and mathematics. Attached to each degree n number field is a rank n -- 1 lattice called its shape. This thesis shows that the shapes of Sn-number fields (of degree n = 3,4, or 5) become equidistributed as the absolute discriminant of the number field goes to infinity. The result for n = 3 is due to David Terr. Here, we provide a unified proof for n = 3, 4, and 5 based on the parametrizations of low rank rings due to Bhargava and Delone--Faddeev. We do not assume any of those words make any kind of sense, though we do make certain assumptions about how much time the reader has on her hands and what kind of sense of humor she has.
