离散交换群上的万有Toeplitz算子代数(英文)

Universal Toeplitz Algebras on Discrete Abelian Groups

设G为一离散交换群，（G，G＋）为一拟偏序群．相应于这样的一个拟偏序群（G，G＋），构造了一个万有Toeplitz算子代数．

Let G be a discrete abelian group and (G,G+ ) a quasi-partially ordered group. In this note, the universal Toeplitz algebra UTG+ (G) associated to such a quasi-partial ordered group is constructed.
