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
In [13], some topological properties of solutions set for (FOSPD) problem in the convex case are established, and in [15], the compactness of the solutions set is obtained in
We can formulate this as an extremal result in two ways: First, for every graph G, among all bipartite graphs with a given number of edges, it is the graph consisting of disjoint
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
Abstract The polycirculant conjecture states that every transitive 2-closed permuta- tion group of degree at least two contains a nonidentity semiregular element, that is, a
