On polar ovals in cyclic projective planes

Kei Yuen Chan, Hiu Fai Law and Philip P. W. Wong

Vol. 12 (2011), No. 1, 35–48
Abstract

A condition is introduced on the abelian difference set D of an abelian projective plane of odd order so that the oval 2D is the set of absolute points of a polarity, with the consequence that any such abelian projective plane is Desarguesian.

Keywords
ovals, polarity, cyclic difference sets, projective planes
