Long-range disassortative correlations in generic random trees

Phys Rev E Stat Nonlin Soft Matter Phys. 2010 Apr;81(4 Pt 1):041136. doi: 10.1103/PhysRevE.81.041136. Epub 2010 Apr 28.

Abstract

We explicitly calculate the distance dependent correlation functions in a maximal entropy ensemble of random trees. We show that correlations remain disassortative at all distances and vanish only as a second inverse power of the distance. We discuss in detail the example of scale-free trees where the diverging second moment of the degree distribution leads to some interesting phenomena.
