The almost-sure population growth rate in branching Brownian motion with a quadratic breeding potential

In this note we consider a branching Brownian motion (BBM) on R{double-struck} in which a particle at spatial position y splits into two at rate βy2, where β>0 is a constant. This is a critical breeding rate for BBM in the sense that the expected population size blows up in finite time while...
