Operator Product Expansions in Non-Perturbative Conformal Bootstraps for 3D Ising Universality Classes

Mathematical Applications of Science Fiction We present a rigorous, non-perturbative derivation of the Op-erator Product Expansion (OPE) convergence bounds withinthe context of the 3D Ising universality class. By leveragingthe axiomatic framework of the Conformal Bootstrap, weconstruct a transfinite sequence of linear functionals actingon the crossing symmetry equations. We prove the exis-tence of a compact ”Ising Island” in the (∆σ , ∆ϵ) plane withprecision exceeding current Monte Carlo methods. We es-tablish eight fundamental lemmas regarding the analyticityof conformal blocks g∆,ℓ(u, v) and the positivity of the OPEcoefficients λ2 σσO . Furthermore, we demonstrate that theunitarity constraints impose a strict hyper-surface boundaryon the allowed parameter space of the Z2-symmetric Confor-mal Field Theory (CFT). This work serves as a foundationalmonograph for the exact solution of the 3D Ising model.
