Analysis of a model describing bacterial colony expansion in radial geometry driven by chemotaxis
European Journal of Applied MathematicsWe investigate a recent model proposed in the literature elucidating patterns driven by chemotaxis, similar to viscous fingering phenomena. Notably, this model incorporates a singular advection term arising from a modified formulation of Darcy’s law.
