Abstract
In this paper, we prove the existence of positive solution for a p-Kirchhoff problem of Brézis-Nirenberg type with singular terms, nonlocal term, and the Caffarelli-Kohn-Nirenberg exponent by using variational methods, concentration compactness, and maximum principle.

It is natural for us to consider the quasilinear Brézis-Nirenberg problem in [10] with nonlocal term and singular weights, ðp > 1, a ≠ 0 and ðα, β, γ, μÞ ≠ ð0, 0, 0, 0ÞÞ: The competing effect of the nonlocal term with the critical nonlinearity and the lack of compactness of the embedding of DαðΩÞ into Lp∗ ðΩ, jxjβp∗ Þ prevent us from using the variational methods in a standard way
Summary
We consider the following p-Kirchhoff problem of Brézis-Nirenberg type with singular terms. In the case p = 2 and α = β = γ = μ = 0, it is analogous to the stationary version of equations that arise in the study of string or membrane vibrations, namely, utt − KðuÞΔu = gðx, uÞ ð3Þ where u denotes the displacement and gðx, uÞ is the external force Equations of this type were first proposed by Kirchhoff in 1883 [1] to describe the transversal oscillations of a stretched string. It is natural for us to consider the quasilinear Brézis-Nirenberg problem in [10] with nonlocal term and singular weights, ðp > 1, a ≠ 0 and ðα, β, γ, μÞ ≠ ð0, 0, 0, 0ÞÞ: The competing effect of the nonlocal term with the critical nonlinearity and the lack of compactness of the embedding of DαðΩÞ into Lp∗ ðΩ, jxjβp∗ Þ prevent us from using the variational methods in a standard way.
