Configuration counting and generating-function summation calculate the nearest-neighbor two-state chain's equilibrium response; the source negative result is isolated from its incorrect spatial extrapolation.
Scientific scope
Configuration counting and generating-function summation calculate the nearest-neighbor two-state chain's equilibrium response; the source negative result is isolated from its incorrect spatial extrapolation. The supported target is a two-state, nearest-neighbor classical chain at positive finite temperature. Its absence of spontaneous magnetization in the stated large-chain limit does not generalize to arbitrary dimensions or interactions. Finite-chain zero-field symmetry alone is not the full thermodynamic argument. Zero temperature, long-range interactions and different spin models are outside scope. Ising’s attempted spatial extension is not adopted; Onsager’s later two-dimensional transition remains a separate contribution. WRS has not independently reconstructed all formulas or certified a physical experiment.
