Abstract
It is known that commutative twisted field planes of odd order have orthogonal polarities, and, for square orders, also unitary polarities, see Dembowski (Finite Geometries, Springer, Berlin, 1968). In this paper, the associated ovals and unitals are considered and their collineation groups are determined.File in questo prodotto:
