We discuss the existence and uniqueness of solution for the second boundary value problem of potential theory often referred to as the Neumann problem, on a gauge ball for the canonical sub-Laplacian in H-type groups. In this way we extend the classical results of the problem as well as its generalization to the Heisenberg group.

H型群中规范球上的Neumann型问题的适定性

我们讨论H型群中规范次拉普拉斯算子的规范球上的势理论第二个边值问题（通常称为诺伊曼问题）的解的存在性和唯一性。这样，我们将问题的经典结果及其推广推广到海森堡小组。
