On polar ovals in cyclic projective planes

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

Full-text: Open access


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