A golden ellipse is an ellipse in which the aspect ratio of its two semi-axes a {\displaystyle a} and b {\displaystyle b} corresponds to the golden ratio. == Equivalent characterization == Given is a annulus with outer radius a {\displaystyle a} and inner radius b {\displaystyle b} as well as an ellipse with semi-major axis a {\displaystyle a} and semi-minor axis b {\displaystyle b} , where a {\displaystyle a} and b {\displaystyle b} are positive real numbers.
