dc.description.abstract | whose solutions correspond to steady states of the Keller-Segel system for chemotaxis. Here B-1(0) is the unit disk,. the outer normal to partial derivative B-1(0), and lambda > 0 is a parameter. We show that, provided lambda is sufficiently small, there exists a family of radial solutions u(lambda) to this system which blow up at the origin and concentrate on partial derivative B-1(0), as lambda -> 0. These solutions satisfy | |
