A Static Exponential Graph

Illustration of the 6 -node static exponential graph and its associated weight matrix. Transform (DFT) and its connection to circulant matrix, which plays the critical role in the proof. Use the conjugate argument then apply the similar procedure as i = 1 . The shape of the 6-node topologies discussed in Sec. The ring topology is undirected, and is illustrated in Figure 1(a).
