摘要：

Quasi-Hermitian varieties V in PG (r,q2) are combinatorial generalizations of the (nondegenerate) Hermitian variety H(r,q2) so that V and H(r,q2) have the same size and the same intersection numbers with hyperplanes. In this paper, we construct a new family of quasi-Hermitian varieties. The isomorphism problem for the associated strongly regular graphs is discussed for r=2.
