      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.
