The parabolic–elliptic Keller–Segel equation in two dimensions provides a fundamental example of a critical aggregation–diffusion model describing chemotactic aggregation and exhibiting a competition between diffusion and concentration. The behavior of solutions strongly depends on the total mass with a critical threshold separating qualitatively different regimes. In this talk I will first review
