An algebraic characterization of projective-planar graphs
نویسندگان
چکیده
We give a detailed algebraic characterization of when a graph G can be imbedded in the projective plane. The characterization is in terms of the existence of a dual graph G on the same edge set as G which satisfies algebraic conditions inspired by homology groups and intersection products in homology groups.

$n$-Array Jacobson graphs
We generalize the notion of Jacobson graphs into $n$-array columns called $n$-array Jacobson graphs and determine their connectivities and diameters. Also, we will study forbidden structures of these graphs and determine when an $n$-array Jacobson graph is planar, outer planar, projective, perfect or domination perfect.
متن کاملAlgebraic characterizations of outerplanar and planar graphs
A drawing of a graph in the plane is even if nonadjacent edges have an even number of intersections. Hanani’s theorem characterizes planar graphs as those graphs that have an even drawing. In this paper we present an algebraic characterization of graphs that have an even drawing. Together with Hanani’s theorem this yields an algebraic characterization of planar graphs. We will also present alge...
متن کاملOn cographic matroids and signed-graphic matroids
We prove that a connected cographic matroid of a graph G is the bias matroid of a signed graph Σ iff G imbeds in the projective plane. In the case that G is nonplanar, we also show that Σ must be the projective-planar dual signed graph of an actual imbedding of G in the projective plane. As a corollary we get that, if G1, . . . , G29 denote the 29 nonseparable forbidden minors for projective-pl...
متن کاملNotes on a theorem of Naji
We present a new proof of an algebraic characterization of circle graphs due to W. Naji. For bipartite graphs, Naji’s theorem is equivalent to an algebraic characterization of planar matroids due to J. Geelen and B. Gerards. Naji’s theorem also yields an algebraic characterization of
متن کاملCounting Labelled Projective-planar Graphs without a K 3,3 -subdivision *
We consider the class F of labelled 2-connected non-planar graphs without a K3,3-subdivision that are embeddable in the projective plane. A method of enumerating these graphs is described. We also enumerate the homeomorphically irreducible graphs in F and homeomorphically irreducible 2-connected planar graphs. The methods are based on the projective-planarity characterization for graphs without...
