Prime-shift operators on Björner's complex of squarefree integers: spectral obstruction, kernel structure, and a Toeplitz–Hankel pipeline for the Guinand–Weil explicit formula
Abstract
Let Δ_n denote Björner's simplicial complex on the squarefree integers m ≤ n and let H_n = Σ_p≤n c_p (T_p + T_p*) be the self-adjoint operator obtained from the prime-shift operators T_p with bounded weights c_p. We present a corrected analysis of H_n and of the Toeplitz pencil constructed from the Guinand–Weil explicit formula. We establish structural properties of H_n, correct several statements of earlier versions, give a closed form for the density of the maximal part of ker A, and revisit the Toeplitz pencil: the prefactor of the prime-power term is 1/(4σ√π), and the value 1/(8πσ√π) of the first revision is withdrawn. We prove an exact-recovery theorem for the pencil and discuss a Hankel–ESPRIT pipeline with its structural bottlenecks. No proof of the Riemann Hypothesis is claimed.
