In Theorem 2.1, we give a combinatorial characterization of non-3-colorable graphs whose polynomial system encoding has a degree one Nullstellensatz certificate of
Likewise we show that any decomposition of the complete graph into strongly regular graphs of (negative) Latin square type is an amorphic association scheme.. We study strongly
If one chooses a sequence of models from this family such that the vertices become uniformly distributed on the metrized graph, then the i th largest eigenvalue of the
Considering n ≥ 3, let us assign to the squares of the chessboard T n , corre- sponding to the vertices of Q(n), the numbers of the cells they belong.. Therefore, the squares
In [RS1] the authors study crossed product C ∗ –algebras arising from certain group actions on ˜ A 2 -buildings and show that they are generated by two families of partial
We then prove the existence of a long exact sequence involving the cohomology groups of a k-graph and a crossed product graph.. We finish with recalling the twisted k-graph C
It is thus often the case that the splitting surface of a strongly irreducible Heegaard splitting of a graph manifold can’t be isotoped to be horizontal or pseudohorizontal in
Additionally, the set of limiting densities of minor-closed graph families is the closure of the set of densities of a certain family of finite graphs, the density- minimal graphs
