The Mean Value Theorem and Uncertainty Principle for theSub-Laplacian on the Quaternionic Heisenberg Group
四元素Heisenberg群上次Laplace算子的平均值定理和不确定原理

In this paper, the mean value theorem for the sub-Laplacianon the quaternionic Heisenberg group is given. As an application, the Hardy inequality and the uncertainty principle are established.
