Relations between the height and the determinant of the Laplacian on t
he space of n-dimensional flat tori and the classical formulas of Kron
ecker and Epstein are established. Extrema of the height are shown to
exist, and results for a global minimum for 2-d tori and a local minim
um for 3-d tori are given, along with more general conjectures of Sarn
ak and Rankin.
