Joint work with P. Debs and D. Le Peutrec
Consider a Galton Watson tree of height $ m $: each leaf has one of $ k $ opinions or not. In other words, for $ i\in \{1,\dots,k\} $, $ x $ at generation $ m $ thinks $ i $ with probability $ {\bf{p}}_i $ and nothing with probability $ {\bf{p}}_0 $. Moreover the opinions are independently distributed for each leaf. Opinions spread along the tree based on a specific rule: the majority wins! In this talk, we study the asymptotic behavior of the distribution of the opinion of the root when $ m\to\infty $.
