Liouville theorem for a class of semilinear elliptic equation on Heisenberg group

We obtain a Liouville type theorem for a class of semilinear subcritical elliptic equation on Heisenberg group. The proof is based on a'priori integral estimate from a generalized differential identity found by Jerison and Lee in 1988. We also get a point-wise estimate near the isolated singularity. This is a joint work with Qianzhong Ou.
