Abstract
We numerically study one-parameter family of random single-cluster
systems. A finite-concentration topological phase transition from
the net-like to the tree-like phase (the latter is without a
backbone) is present in all models of the class. Correlation
radius index νB of the backbone in the net-like phase; graph
dimensions - of the tree-like phase, and of
the backbone in the net-like phase appear to be universal within
the accuracy of our calculations, while the
backbone fractal dimension DB is not universal: it depends on the
parameter of a model.
