In this paper, the following critical Kirchhoff-type elliptic equation involving a logarithmic-type perturbation

(a+bΩ|u|2dx)Δu=λ|u|q2uln|u|2+μ|u|2u

is considered in a bounded domain in R4. One of the main obstructions one encounters when looking for weak solutions to Kirchhoff problems in high dimensions is that the boundedness of the (PS) sequence is hard to obtain. By combining a result by Jeanjean [27] with the mountain pass lemma and Brézis–Lieb's lemma, it is proved that either the norm of the sequence of approximation solutions goes to infinity or the problem admits a nontrivial weak solution, under some appropriate assumptions on a, b, λ, and μ.
