Conjecture on deep Ricci-flat Kähler minima in Calabi–Yau moduli space

Let Al(M)\mathop{\rm Al}(M) denote the relevant space of metrics, and let c1c_1 and nn be the diameter-bound parameters for a fixed Ricci-flat Kähler metric ω0\omega_0. A local minimum is β\beta-deep when its depth is measured by a computably enumerable degree of unsolvability β\beta. Deep Ricci-flat Kähler minima conjecture. There exists a unique functional on the space Al(M)\mathop{\rm Al}(M) such that the local minima are β\beta-deep for β\beta a computably enumerable degree of unsolvability. Furthermore, the local minima are given by Ricci-flat Kähler metrics and parametrized by varying Kähler and complex moduli. The number of β\beta-deep local minima with diameter bounded by c1c_1 and nn, for fixed ω0\omega_0, is an exponential of a polynomial in c1c_1 and nn.

This conjecture is proposed by analogy with a theorem about fractal structure in the space of metrics, in the setting of computationally difficult Ricci-flat metric construction on Calabi–Yau manifolds. The supplied source does not establish the claim or provide evidence resolving it.
