題　目：The Heat Kernel and Green Function of the Sub-Laplacian on the
          Heisenberg Group

摘　要： After a brief recall of the basics of the first lecture, the heat kernels
and Green functions of the twisted Laplacians are constructed explicitly
using Weyl transforms. They are then used to construct the explicit
formulas for the heat kernel and Green function of the sub-Laplacian on
the Heisenberg group. The meaning of the Green function in sub-Riemannian
geometry is then given leading to the notion of the Carnot-Caratheodory
metric.
