Abstract:
In my talk I will present results concerning a branching system as
follows. Particles evolve according to a Levy motion with heavy tails.
They branch according to dyadic branching law. We consider three
different regimes of the branching rate:
- constant, then the size system grows exponentially. The speed of the
right-most particle differs from
- \beta \log, then the size of the system grows as exp(exp(\beta/(e \alpha)t)),
- \log^{1+\epsilon}, then almost surely the system explodes, i.e.
produces infinite number of particles in finite time.
 
These are joint results with Simon Harris (University of Bath)
