Consider the base case: If no energy is concentrating at a point along the sphere, then no ghost bubble is going to form there, the renormalization process does nothing. It’s only when you had energy concentrating at some point that you’ll get a bubble tree based at that point, so the concentrated energy is now somewhere in that tree and we repeat the process. | |

I must apologise in advance but I still don't see why I can't just keep on attaching ghost bubbles to ghost bubbles. I think the problem in my understanding is that, in the presence of Ghost bubbles, I don't clearly see why every iteration of this procedure costs $\hslash$ energy. Because if the procedure has to end, by lemma 4.2 I agree that eventually there must be a non-constant bubble that "ends" the branch of my tree. | |
