We consider the following Kirchhoff type problem involving a critical nonlinearity:
⎧ $-[a+b(∫_{Ω} |∇u|²dx)^{m}]Δu = f(x,u) + |u|^{2*-2}u$ in Ω,
⎨
⎩ u = 0 on ∂Ω,
where $Ω ⊂ ℝ^{N}$ (N ≥ 3) is a smooth bounded domain with smooth boundary ∂Ω, a > 0, b ≥ 0, and 0 < m < 2/(N-2). Under appropriate assumptions on f, we show the existence of a positive ground state solution via the variational method.
