Low-h nonattainment conjecture for Néel-wall energies at winding number d minus alpha over pi

Let dN{1}d\in\mathbb{N}\setminus\{1\}, and let Eh(w)\mathcal{E}_h(w) denote the infimum of the energy among profiles with winding number ww. Low-hh nonattainment conjecture. There exists K(0,1)K\in(0,1) such that Eh(dα/π)\mathcal{E}_h(d-\alpha/\pi) is not attained for every h[0,K]h\in[0,K]. This complements the conjectured attainment near h=1h=1 and excludes d=1d=1, for which the claim is not asserted.
