中文摘要	In this paper, we consider the principal eigenvalue problem for Hormander's Laplacian on R-n, and we find a comparison principle for such principal eigenvalues. We also study a related semi-linear sub-elliptic equation in the whole R-n and prove that, under a suitable condition, we have infinitely many positive solutions of the problem.
