中文摘要：

在Heisenberg群上的有界区域Ω上定义了Royden少代数（p〉1），进而证明了Heisenberg群上的两个有界区域拟共形等价的充要条件是它们的Royden（2n＋2）-代数是Banach代数同构．

英文摘要：

The definition of Royden p-algebra（p〉1） for the bounded domain Ω in Heisenberg group is given, and it is showed that two bounded domains are quasiconformally equivalent if and only if their Royden （2n＋ 2）- algebras are isomorphic as Banach algebras.
