Title: Coalescence in rapidly growing Galton Watson trees
Abstract of Talk
Consider a Galton Watson tree. Go to the $n$th generation. Pick two individuals at random from those in the $n$th generation. Trace their lines back till they meet. Call that generation $X_n$. We find the limit distribution of $X_n$ for all the four cases: supercritical, critical, subcritical, explosive.
