On the Spectra of Real and Complex Lamé Operators

William A. Haese-Hill, Martin A. Hallnäs, Alexander P. Veselov

We study Lamé operators of the form $L = - \frac{d ^{2}}{d x ^{2}} + m (m + 1) ω^{2} ℘ (ω x + z_{0}),$ with $m \in N$ and $ω$ a half-period of $℘ (z)$ . For rectangular period lattices, we c…

Complex exceptional orthogonal polynomials and quasi-invariance

William A. Haese-Hill, Martin A. Hallnäs, Alexander P. Veselov

Consider the Wronskians of the classical Hermite polynomials $H_{λ, l} (x) := Wr (H_{l} (x), H_{k_{1}} (x), \dots, H_{k_{n}} (x)), l \in Z_{\geq 0},$ where $k_i=λ_i+n-i,…
