A black-box random-walk proof establishes mean-field near-critical decay |x|^{-d+2+ε} exp(-c|x|/ξ) for two-point functions on Z^d (d>2) under a short list of assumptions, covering self-avoiding walk, percolation, Ising, XY, |φ|^4 and lattice trees above their upper critical dimensions.

A controlled ε-δ expansion around the LR-SR boundary yields two-loop expressions for ν, η_ω and η_k in long-range quantum O(n) models together with a proposed universality diagram.
Adele-valued random walks converge weakly to an adelic Lévy process in the J1 Skorokhod topology after appropriate scaling.
Proves unique phase transition and critical exponents for percolation on hierarchical lattices, with results on the infinite limit graph, noise sensitivity, and a fixed-point condition for monotone Boolean functions.
