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.
