Active-to-absorbing-state phase transition in an evolving population with mutation
arXiv:1510.01494 · doi:10.1103/PhysRevE.92.042110
Abstract
We study the active to absorbing phase transition (AAPT) in a simple two-component model system for a species and its mutant. We uncover the nontrivial critical scaling behavior and weak dynamic scaling near the AAPT that shows the significance of mutation and highlights the connection of this model with the well-known directed percolation universality class. Our model should be a useful starting point to study how mutation may affect extinction or survival of a species.
