Talagrand's orthogonal structures conjecture for mixed p-spin glasses

From papers

Let GNG_N be the Gibbs measures of a mixed pp-spin glass model on the hypercube with zero external field. The model admits an Orthogonal Structure if there is a sequence (ak)k0(a_k)_{k\geq 0} with ak>0a_k>0 such that, for every k0Nk_0\in\mathbb{N} and every positive ϵ\epsilon, there is an N0N_0 such that for NN0N\geq N_0, with probability at least 3/43/4, there is a random collection of sets {Ak,N}kk0ΣN\{A_{k,N}\}_{k\leq k_0}\subset\Sigma_N satisfying

GN(Ak,N)akG_N(A_{k,N})\geq a_k

and, for every distinct k,lk0k,l\leq k_0,

R12\mathbbm1σ1Ak,N,σ2Al,N<ϵ.\left\langle\lvert R_{12}\rvert\mathbbm{1}_{\sigma^1\in A_{k,N},\sigma^2\in A_{l,N}}\right\rangle<\epsilon.

Talagrand conjectured that, at zero external field, mixed pp-spin glass models admit such orthogonal structures. This conjecture is proved in the source by the stated low-temperature theorem.
