Consider the two-dimensional Ising model in the complete wetting regime with $h\geq h_{\mathrm{w}}(\beta)$ and positive bulk field $\lambda$. Let $\gamma^+$ be the upper envelope o…

For the two-dimensional Ising model with bulk field $\lambda\geq 0$, let $w(\lambda;\beta,h)$ denote the average thickness of the layer of unstable $-$ phase, and let…
