Oscillation conjecture for Berezin-transform eigenvalues at fixed weight deficit

About 5 years old · traced to

Let jj be a positive parameter, let d∈Nd\in\mathbb{N}, and set m=j−dm=j-d. Let λ(0),λ(1),…,λ(2j)\lambda^{(0)},\lambda^{(1)},\ldots,\lambda^{(2j)} be the eigenvalues of the Berezin transform Bj,j−d\mathcal{B}_{j,j-d}. Oscillation conjecture. For every d∈Nd\in\mathbb{N} there exists j0j_0 such that for all j≥j0j\geq j_0, the sequence

λ(0),λ(1),λ(2),…,λ(2j)\lambda^{(0)},\lambda^{(1)},\lambda^{(2)},\ldots,\lambda^{(2j)}

has dd local minima and dd local maxima. This predicts a precise eventual oscillation pattern in the spectrum for each fixed weight deficit, based on the numerical plots described in the source. Its status is not resolved in the supplied source.
