Pattern Formation in a Bacterial Colony Model

الملخص EN

We investigate the spatiotemporal dynamics of a bacterial colony model.

Based on the stability analysis, we derive the conditions for Hopf and Turing bifurcations.

Furthermore, we present novel numerical evidence of time evolution of patterns controlled by parameters in the model and find that the model dynamics exhibit a diffusion controlled formation growth to spots, holes and stripes pattern replication, which show that the bacterial colony model is useful in revealing the spatial predation dynamics in the real world.
