| Abstract: | In this paper, we introduce the notion of wedge product of Schur rings. We show that for any nontrivial Schur ringS over a cyclic groupG, if there is a subgroupH such that Σ g ε H g Σ g∈H g ∉S, thenS is either a dot product or wedge product for some Schur rings over smaller cyclic groups. |
