Heisenberg群上曲线族模的一个估计

An estimating of the modulus of a curve family on the Heisenberg group

类比欧几里德空间上的曲线族的模的著名的比较原理,得到了Heisenberg群上的估计曲线族模的一个不等式.

On the analogue of a well-known theorem of a comparison principle for modulus on Euclidean space,it is obtained a method for estimating the modulus of a path family on the Heisenberg group.
