Divergence Symmetries of Critical Kohn-Laplace Equations on Heisenberg groups

arXiv:math/0703698

Abstract

We show that any Lie point symmetry of semilinear Kohn-Laplace equations on the Heisenberg group H^1 with power nonlinearity is a divergence symmetry if and only if the corresponding exponent assumes critical value.
