Abstract
Nonlinear dynamics near an unstable constant equilibrium in a Keller-Segel model with the source term up(1-u) is considered. It is proved that nonlinear dynamics of a general perturbation is determined by the finite number of linear growing modes over a time scale of ln(1/δ), where δ
is a strength of the initial perturbation.
