Pseudo and strongly pseudo 2-factor isomorphic regular graphs and digraphs
A graph G is pseudo 2–factor isomorphic if the parity of the number of cycles in a 2–factor is the same for all 2–factors ofG. In [3] we proved that pseudo 2–factor isomorphic k–regular bipartite graphs exist only for k ≤ 3. In this paper we generalize this result for regular graphs which are not necessarily bipartite. We also introduce strongly pseudo 2–factor isomorphic graphs and we prove th...
متن کاملPseudo 2-factor isomorphic regular bipartite graphs
A graph is pseudo 2–factor isomorphic if the numbers of circuits of length congruent to zero modulo four in each of its 2–factors, have the same parity. We prove that there exist no pseudo 2–factor isomorphic
متن کاملStrongly regular and pseudo geometric graphs
Very often, strongly regular graphs appear associated with partial geometries. The point graph of a partial geometry is the graph whose vertices are the points of the geometry and adjacency is defined by collinearity. It is well known that the point graph associated to a partial geometry is a strongly regular graph and, in this case, the strongly regular graph is named geometric. When the param...
متن کاملIrreducible pseudo 2-factor isomorphic cubic bipartite graphs
A bipartite graph is pseudo 2–factor isomorphic if all its 2–factors have the same parity of number of circuits. In a previous paper we have proved that pseudo 2–factor isomorphic k–regular bipartite graphs exist only for k ≤ 3, and partially characterized them. In particular we proved that the only essentially 4–edge-connected pseudo 2–factor isomorphic cubic bipartite graph of girth 4 is K3,3...
متن کاملLocally Pseudo-Distance-Regular Graphs
The concept of local pseudo-distance-regularity, introduced in this paper, can be thought of as a natural generalization of distance-regularity for non-regular graphs. Intuitively speaking, such a concept is related to the regularity of graph 1 when it is seen from a given vertex. The price to be paid for speaking about a kind of distance-regularity in the non-regular case seems to be locality....
