摘要
An abstract version of concentration compactness on Hilbert spaces applies to to actions of non-compact Lie groups. Using the concentration-compactness argument we prove existence of solutions for semilinear problems involving sub-Laplacians on the whole Lie group and on their certain non-compact subsets, including minimizers for Sobolev inequalities. The result is stated for any real connected finite-dimensional Lie group.
