A projective analogue of Napoleon's and Varignon's theorems
Quang-Nhat Le
What do Napoleon's and Varignon's theorems have in common? We claim that they both are examples of immediately regularizing natural polygon iterations in different planar geometrie…
Macdonald's solid-angle sum for real dilations of rational polygons
Quang-Nhat Le, Sinai Robins
The solid-angle sum of a rational polytope , with was first investigated by I.G. Macdonald. Using our F…
Fourier transforms of polytopes, solid angle sums, and discrete volume
Ricardo Diaz, Quang-Nhat Le, Sinai Robins
Given a real closed polytope , we first describe the Fourier transform of its indicator function by using iterations of Stokes' theorem. We then use the ensuing Fourier transfor…
A family of projectively natural polygon iterations
Quang-Nhat Le
The pentagram map was invented by Richard Schwartz in his search for a projective-geometric analogue of the midpoint map. It turns out that the dynamical behavior of the pentagram…
