Abstract
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
