A subset of the Hermitian surface

Giorgio Donati and Nicola Durante
Vol. 3 (2006), No. 1, 13–23
DOI: 10.2140/iig.2006.3.13
Abstract

In this paper we define a ruled algebraic surface of PG(3,q2), called a hyperbolic Qℱ-set and we prove that it is contained in the Hermitian surface of PG(3,q2). Also, we characterise a hyperbolic Qℱ-set as the intersection of two Hermitian surfaces.

Keywords
