A Model for Branch Competition

  • Thomas C. Halsey


Branching (or tip-splitting) is a ubiquitous feature of growth processes in nature. We introduce a simple model, linear in growth probabilities, of branch competition that combines tip-splitting processes, local screening, and extinction of branches whose growth has come to an end. This model admits an exact solution; which is corroborated by numerical results. An extension of the model that depends quadratically upon growth probabilities exhibits a phase transition, with non-trivial scaling in the neighborhood of that transition.

I am grateful to Prof. Ray Goldstein for his hospitality during a visit to the Department of Applied Mathematics and Theoretical Physics at Cambridge University, which afforded me time to organize my thoughts on this topic.
