Title:
Induced Forests in Bipartite Planar Graphs
Time & Venue:
2015.6.17 10:40-11:40am N613
Abstract:
Akiyama and Watanabe, and independently, Albertson and Haas conjectured that every simple planar bipartite graph on n vertices contains an induced forest on at least 5n/8. In this talk, we apply the discharging method to bipartite planar graphs and show that every simple bipartite planar graph on n vertices contains an induced forest on at least (4n + 3)/7 vertices. (Joint work with Qiqin Xie and Xingxing Yu).
