摘要：
We show that if a connected graph with n nodes has conductance phi then rumour spreading, also known as randomized broadcast, successfully broadcasts a message within O(log(4) n/phi(6)) many steps, with high probability, using the PUSH-PULL strategy. An interesting feature of our approach is that it draws a connection between rumour spreading and the spectral sparsification procedure of Spielman and Teng [23].
