拟序群上的Toephiz C~* -代数的忠实表示的刻划(英文)

On the Faithful Representations of Toeplitz C~* -Algebras on Quasily Ordered Groups

设G为一离散群，（G，P）为一个拟序群．记T（G，P）为相应的ToeplitzC-代数．给出了T（G，P）的一个表示为忠实的充要条件．

Let G be a discrete group and (G,P) a quasily ordered group. T (G,P)denotes the corresponding Toeplitz C -algebra. A necessary and suffcient conditionfor a faithful representation of T (G,P ) is given.
