The best constant in Hardy inequality for the sub-Laplacian is determined.In Chapter Two, some integral identities on groups of Heisenberg type are established. A nonexistence result for posotive solutions of semilinear sub-Laplace equations on groups of Heisenberg type is obtained.In Chapter Three, a Carleman estimation for the sub-Laplacian on groups of Heisenberg type is found and a unique continuation theorem is proved. | Keywords/Search Tags: | groups of Heisenberg type, Hardy inequality, Pohozaev identity, nonexistence, Carleman estimation, unique continuation | PDF Full Text Request | Related items |
