英文摘要	This paper is concerned with the uniqueness of solutions to the following nonlocal semi-linear elliptic equationwhere omega is a bounded domain in and are positive parameters. The above equation arises as the stationary problem of the well-known classical Keller-Segel model describing chemotaxis. For Eq. () with Neumann boundary condition, we establish an integral inequality and prove that the solution of Eq. () is unique if and u satisfies some symmetric properties. While for Eq. (*) with Dirichlet boundary condition, the same uniqueness result is obtained without symmetric condition by a different approach inspired by some recent works (Gui and Moradifam, 2018, Invent. Math. 214(3):1169-1204; Gui and Moradifam, Proc. Am. Math. Soc. 146(3):1231-1124). As an application of the uniqueness results, we prove that the radially symmetric solution of the classical Keller-Segel system with subcritical mass subject to Neumann boundary conditions will converge to the unique constant equilibrium as time tends to infinity if omega is a disc in two dimensions. As far as we know, this is the first result that asserts the exact asymptotic behavior of solutions to the classical Keller-Segel system with subcritical mass in two dimensions.
