We study the following nonlinear elliptic equation
where tex2html_wrap_inline24 is a smooth bounded domain in tex2html_wrap_inline26. This equation arises in the study of stationary solutions of a chemotaxis system proposed by Keller and Segel. Under the condition that tex2html_wrap_inline28 for m=1,2,..., where tex2html_wrap_inline32 is the first (nonzero) eigenvalue of tex2html_wrap_inline34 under the Neumann boundary condition, we establish the existence of a solution to the above equation. Our idea is a combination of Struwe's technique and blow up analysis for a problem with Neumann boundary condition.
