Analytic approach to the evolutionary effects of genetic exchange
Elisheva Cohen, David A. Kessler, Herbert Levine
We present an approximate analytic study of our previously introduced model of evolution including the effects of genetic exchange. This model is motivated by the process of bacter…
Front Propagation up a Reaction Rate Gradient
Elisheva Cohen, David A. Kessler, Herbert Levine
We expand on a previous study of fronts in finite particle number reaction-diffusion systems in the presence of a reaction rate gradient in the direction of the front motion. We st…
Front Propagation Dynamics with Exponentially-Distributed Hopping
Elisheva Cohen, David A. Kessler
We study reaction-diffusion systems where diffusion is by jumps whose sizes are distributed exponentially. We first study the Fisher-like problem of propagation of a front into an…
