Abstract:
We propose a continuum treatment of random networks with odd rings near the antibonding bound. An analogy with nematic liquid crystals is demonstrated in which Rivier lines play the role of disclination lines. The state density is expressed in terms of fluctuations of gauge fields associated with Rivier lines.
