Abstract
Let Va(F) be the orthogonal geometry of dimension n over Fq, where q is a power of 2 and q> 2. Let A be the arrangement in V. (Fq) consisting of all (n-1)-dimensional non- singular subspaces of V.(Fq) and let L(A) be the geometric lattice consisting of all intersections of elements of A. In this paper we give a characterization of the elements of L(A) and compute the characteristic polynomial of L(A).
