Abstract
Using a variation of Seydewitz’s method of projective generation of quadrics we define two algebraic surfaces of , called elliptic -sets and semi-hyperbolic -sets, and we show that these surfaces are contained in the Hermitian surface of . Also, we characterize a semi-hyperbolic -set as the intersection of two Hermitian surfaces. Finally we describe all possible configurations of the absolute set of an -correlation in , where is the involutory automorphism of .
