Existence and classification of positive solutions for coupled purely critical Kirchhoff system (Q6611253)

This paper is concerned with the study of a Kirchhoff system involving a critical exponent. By using suitable transformations of the problem into different types of constrained variational problems based on the width of the Hartree kernel, the authors give a complete classification of positive ground-state solutions for the Kirchhoff system, where they establish several existence, multiplicity and asymptotic results under suitable conditions on the corresponding parameters.
