Riesz Means of Dirichlet Eigenvalues for the Sub-Laplace Operator on the Engel Group


In this paper, we are concerned with the Riesz means of Dirichlet eigenvalues for the sub-Laplace operator on the Engel group and deriver different inequalities for Riesz means. The Weyl-type estimates for means of eigenvalues are given.
