Abstract
We consider the boundary-value problem {equation presented}, where Br0 is the ball of radius r0 in RN, N ≥ 2, λ > 0 and v is the outer normal derivative at ∂Br0 . This problem is equivalent to the stationary Keller-Segel system from chemotaxis. We show the existence of a solution concentrating at the boundary of the ball as λ goes to 0.File in questo prodotto:
