Polarities and planar collineations of Moufang planes
The authors study collineations and correlations of Moufang planes. They show that conjugacy classes of Baer involutions are not refined if one restricts the conjugating element to the stabilizer of a quadrangle, and then they establish an interrelation between Baer involutions and polarities. Finally, they use their results to prove a transitivity result for centralizers of polarities (Theorem 5.3).
