Table-profile formulas for universal finite-size scaling

For the models self-avoiding walk, Ising, φ4|\varphi|^4, percolation, and branched polymers, let f(s)f(s) denote the torus susceptibility and plateau profile in the critical window, with SR and LR versions sharing the same profile. Let dc,αd_{\mathrm{c},\alpha} be the relevant upper critical dimension.

Table-profile conjecture. The profile functions f(s)f(s) are the functions listed in Table~ for both SR and LR models in every dimension ddc,αd\ge d_{\mathrm{c},\alpha}, including the upper critical dimension.

The claim identifies the universal profiles more explicitly than the preceding scaling conjecture. The source gives complete-graph and hierarchical-lattice evidence for some profiles but does not state that the general lattice claim has been proved.
