*A Sharp Lower Bound On The Polygonal Isoperimetric Deficit*

##### Authors:

##### Abstract:

It is shown that the isoperimetric deficit of a convex polygon P admits a lower bound in terms of the variance of the radii of P, the area of P, and the variance of the barycentric angles of P. The proof involves circulant matrix theory and a Taylor expansion of the deficit on a compact manifold.##### Get the paper in its entirety
