Abstract
In this paper, we give a rigorous proof for the expression of the angle between adjacent sides in the skew polygons appearing at rational times in the evolution of regular polygons of sides under the vortex filament equation. The proof depends on showing that some exponential sums with arithmetic content are purely imaginary.
