SUMMARY:Atlantic Graph Theory Seminar
DESCRIPTION:The 2-burning number of a graph\nSpeaker: Ann Trenk\, Wellesley College\n\nAbstract:\nWe discuss a discrete-time model for the spread of information in a graph\, motivated by the idea that people believe a story when they learn of it from two different origins. Similar to the burning number\, in this problem\, information spreads in rounds and a new source can appear in each round. For a graph $G$\, we are interested in $b_2(G)$\, the minimum number of rounds until the information has spread to all vertices of graph $G$. We are also interested in finding $t_2(G)$\, the minimum number of sources necessary so that the information spreads to all vertices of $G$ in $b_2(G)$ rounds. In addition to discussing general results\, we find $b_2(G)$ and $t_2(G)$ for the classes of spiders and wheels and show that their behavior differs with respect to these two parameters.\n\nThis is joint work with Catherine Jacobs (Wellesley College) and Margaret-Ellen Messinger (Mount Allison University).\n \nZoom link:\nhttps://us02web.zoom.us/j/86861499971?pwd=rTDAaju0TCu24asnaBGvkuNlT11KZ1.1\n\nMeeting ID: 868 6149 9971\nPasscode: 325258
