Abstract
Assume that \({\mathcal{L}}_\alpha = - \frac{1}{2}\sum\nolimits_{j = 1}^n {(Z_j \bar Z_j + \bar Z_j Z_j ) + i\alpha T} \) is the sub-Laplacian on the nonisotropic Heisenberg group H n ;Z j ,Z j for j = 1, 2, …,n and T are the basis of the Lie algebra h n .We apply the Laguerre calculus to obtain the explicit kernel for the fundamental solution of the powers of L α and the heat kernel exp{−sL α }.Estimates for this kernel in various function spaces can be deduced easily.
