Existence of a positive ground state solution for a Kirchhoff type problem involving a critical exponent
We consider the following Kirchhoff type problem involving a critical nonlinearity: ⎧ in Ω, ⎨ ⎩ u = 0 on ∂Ω, where (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.
