Delone sets associated with badly approximable triangles

Number Theory 2025-03-18 v4

Abstract

We construct new Delone sets associated with badly approximable numbers which are expected to have rotationally invariant diffraction. We optimize the discrepancy of corresponding tile orientations by investigating the linear equation x+y+z=1x+y+z=1 where πx\pi x, πy\pi y, πz\pi z are three angles of a triangle used in the construction and xx, yy, zz are badly approximable. In particular, we show that there are exactly two solutions that have the smallest partial quotients by lexicographical ordering.
