Abstract: Gossip, as we all know, spreads like wildfire. In this talk we establish this dictum mathematically, starting from an empirical property of social networks: high conductance. An interesting aspect of our proof is that it draws a connection with the spectral sparsification theory of Spielman and Teng.
