| Abstract： | I will talk about how to get a sharp lower bound estimate for the first nonzero eigenvalue of the sublaplacian, Kohn Laplacian, and Folland- Stein operator, on a closed pseudohermitian (2n+1)-manifold. We also discuss the case when a sharp lower bound estimate of the sublaplacian or Kohn Laplacian is achieved. |
