Hajós’ conjecture and cycle power graphs

Spanning trees in directed circulant graphs and cycle power graphs

“…where in the last equality we used equation (3). Putting equations (8), (9) and (10) |z k | n 2 n−1 sin(π(n + 1)k/β + nθ k ).…”

“…As a consequence, the asymptotic behaviour of it is derived. Cycle power graphs appear, for example, in graph colouring problems, see [9,10].…”
