| contents | The short-distance asymptotics of the generating functional for $n$-point correlators of twist-$2$ operators in $\mathcal{N}=1$ supersymmetric (SUSY) SU($N$) Yang-Mills (SYM) theory were recently calculated in [1,2]. This calculation depends on a change of basis for renormalized twist-$2$ operators, in which $-γ(g)/ β(g)$ reduces to $γ_0/ (β_0\,g)$ at all orders in perturbation theory, where $γ_0$ is diagonal, $γ(g) = γ_0 g^2+\ldots$ is the anomalous-dimension matrix, and $β(g) = -β_0 g^3+\ldots$ is the beta function. The method is founded on a new geometric interpretation of operator mixing [3], assuming that the eigenvalues of the matrix $γ_0/ β_0$ meet the nonresonant condition $λ_i-λ_j\neq 2k$, with the eigenvalues $λ_i$ ordered nonincreasingly and $k\in \mathbb{N}^+$. This nonresonant condition was numerically verified for $i,j$ up to $10^4$ in [1,2]. In this work, we employ techniques initially developed in [4] to present a number-theoretic proof of the nonresonant condition for twist-$2$ operators, fundamentally based on the classic result that Harmonic numbers are not integers. |
