In this talk continuation of the degenerate Keller Segel model after the blow up ,that is concentration of mass is discussed.The key is a renormalization of the chemotactic drift.It turns out that this renormalization is not unique.So we get several possible evolution equations for the evolution of (varifold like)measures after the blowup time.

Joint work with Y.Sugiyama and J.J.L. Velazquez.
