On the existence of radially symmetric blow-up solutions for the Keller-Segel model.
We investigate the existence of radially symmetric solutions of the Keller-Segel model [abstract see text] which blow up in finite or infinite time, i.e.[abstract see text] for T(max) < or = infinity, under a larger class of initial data than in [10] and [11].
