In the past twenty years , toeplitz operators denned on discrete groups have been investigated by many mathematicians such as a . nica [ 7 ] m . laca [ 4 ] [ 16 ] " , i . raeburn [ 5 ] etc . the main object of this paper is , based on clarifying the induced ideals , to show that some toeplitz algebras are purely infinite provided that a certain condition is satisfied
在过去的几十年中，许多数学工作者(例如a . nica , m . laca , i . raeburn等)都对定义在离散群上的toeplitz代数作了深入而且广泛的研究。本文的主要目的是通过对相关toeplitz代数的诱导理想的刻划来研究toeplitz代数的纯无限性质。
