We show that if A is a non-unital \(C^*\)-algebra of compact operators, which is \( *\)-isomorphic to \(\oplus _{i \in I} K(H_{i})\), where I is an arbitrary index set and for every \( i \in I \), \(H_{i} \) is a separable Hilbert space, then there exists a Hilbert \(A_1\)-module admitting no frames, where \(A_1\) is the unitization of A.

我们证明,如果A是紧凑算子的非单位\(C ^ * \)-代数,它是\(* \)-同构于\(\ oplus _ {i \ in I} K(H_ {i} )\),其中我是一个任意索引集,并且对于每个\(i \ in I \),\(H_ {i} \)是一个可分离的希尔伯特空间,然后存在一个希尔伯特\(A_1 \)-模块允许没有框架,其中\(A_1 \)是A的单位。
