摘要
We study the geometry of involutions of the finite unitary group P Gamma U(n + 1, q(2)). The configurations of fixed singular points, fixed singular lines and fixed symplectic subgeometries in the case n = 3, are provided. This allows us to describe the geometry of linear involutions of PGO(-) (6, q). (C) 2015 Elsevier Inc. All rights reserved.
