High thresholds yield convergence of opinions toward an average opinion, whereas low thresholds result in several opinion clusters. The model is further generalized to network interactions, threshold heterogene...

Certain properties of the network of departure Ns and the padding network NP of an (n + I&node resistive n-port network containing no negative conductances are established. Based on these properiies, some necessary conditions and a sufficient condition for the realizability of the Y matrices of (n + 2J-node resistive n-port nehvorks ore obtained. A new proof for the supremacy condition is given...
