Large scale properties of the IIIC for 2D percolation

We reinvestigate the 2D problem of the inhomogeneous incipient infinite cluster   where, in an independent percolation model, the density decays to _pc$p_c$ with an inverse power, λ$\lambda$, of the distance to the origin. Assuming the existence of critical exponents (as is known in the case of the triangular site lattice) if the power is less than 1/ν$1/\nu$, with ν$\nu$ the correlation length exponent, we demonstrate an infinite cluster with scale dimension given by _DH=2−βλ$D_H=2-\beta \lambda$. Further, we investigate the critical case _λc=1/ν${\lambda }_c=1/\nu$ and show that iterated logarithmic corrections will tip the balance between the possibility and impossibility of an infinite cluster.
