Covers of Point-Hyperplane Graphs
نویسنده
چکیده
A cover of the non-incident point-hyperplane graph of projective dimension 3 for fields of characteristic 2 is constructed. For fields F of even order larger than 2, this leads to an elementary construction of the non-split extension of SL4(F) by F6.

3 Covers of Point - Hyperplane Graphs
We construct a cover of the non-incident point-hyperplane graph of projective dimension 3 for fields of characteristic 2. If the cardinality of the field is larger than 2, we obtain an elementary construction of the non-split extension of SL 4 (F) by F 6 .
متن کاملLocal Recognition Of Non-Incident Point-Hyperplane Graphs
Let P be a projective space. By H(P) we denote the graph whose vertices are the non-incident point-hyperplane pairs of P, two vertices (p,H) and (q, I) being adjacent if and only if p ∈ I and q ∈ H. In this paper we give a characterization of the graph H(P) (as well as of some related graphs) by its local structure. We apply this result by two characterizations of groups G with PSLn(F) ≤ G ≤ PG...
متن کاملÉtale Covers of Affine Spaces in Positive Characteristic
We prove that every projective variety of dimension n over a field of positive characteristic admits a morphism to projective n-space, étale away from the hyperplane H at infinity, which maps a chosen divisor into H and a chosen smooth point not on the divisor to some point not in H .
متن کاملRandom Walks on Directed Covers of Graphs
Directed covers of finite graphs are also known as periodic trees or trees with finitely many cone types. We expand the existing theory of directed covers of finite graphs to those of infinite graphs. While the lower growth rate still equals the branching number, upper and lower growth rates do not longer coincide in general. Furthermore, the behaviour of random walks on directed covers of infi...
متن کاملAutomorphism Groups of Certain Unstable Graphs
The automorphism groups of the canonical double covers of the unstable graphs in two infinite families are considered. These graphs are important from the point of view of algebraic map theory as they can be embedded into regular oriented maps.
