題　目：The Sub-Laplacian on the Heisenberg Group

摘　要： We begin with the Heisenberg group and construct the sub-Laplacian. Using
Fourier-Wigner transforms, we obtain a one-parameter family of twisted
Laplacians, each of which can be diagonalized using suitably dilated Hermite
functions. The solutions of the heat equation and the Poisson equation for
the sub-Laplacian are then formulated in terms of the heat kernel and
Green function respectively. They are then shown to be related to the heat
kernels and Green functions of the twisted Laplacians.
