Equichordal Point Problem
 | A major contributor to this article appears to have a close connection with its subject. (November 2010) |
In convex geometry, the equichordal point problem asks whether there exists a curve with two equichordal points. The problem was originally posed in 1916 by Fujiwara[1], and solved by Marek Rychlik in 1996[2]. The answer in the negative is the subject of Rychlik's theorem.
