Construction of Four Completely Independent Spanning Trees on Augmented Cubes
Let T1, T2,..., Tk be spanning trees in a graph G. If for any pair of
vertices {u, v} of G, the paths between u and v in every Ti( 0 < i < k+1) do
not contain common edges and common vertices, except the vertices u and v, then
T1, T2,..., Tk are called completely independent spanning trees in G. The
n-dimensional augmented cube, denoted as AQn, a variation of the hypercube
possesses several embeddable properties that the hypercube and its variations
do not possess. For AQn (n > 5), construction of 4 completely independent
spanning trees of which two trees with diameters 2n - 5 and two trees with
diameters 2n - 3 are given
