Scale free power law
WebMay 11, 2010 · Not any power makes a power law scale free, though. In three dimensions the power law is actually scale free only for γ < 3, whereas if γ > 3 the correlation length does not scale linearly with L and the correlation is effectively short ranged. As we have seen in the main text, to have a good agreement with the biological data we need to use ... Webmon feature that the distribution of their local connectivity is free of scale, following a power-law for large k, with an exponent γ between 2.1 and 4 which is unexpected within the framework of the existing network models. The random graph model of ER (7) assumes that we start with N vertices, and connect each pair of vertices with ...
