A remark on Chebyshev rational functions, multipoint Padé approximants and Noise
Maxim Derevyagin, Max Meynig
The paper studies Chebyshev rational functions and shows how they generate multipoint Padé approximants, providing recurrence relations and a Thiele-type continued fraction, and ex…

Generating and Computing Quantum Periods in Exact WKB
Max Meynig
Periods of rational integrals appear in quantum mechanics through asymptotic expansions of traces computed with the semiclassical symbol calculus. We develop a novel formal series…

Non-perturbative asymptotics of the eigenvalues of the spheroidal equation
Max Meynig
New non-perturbative results on the eigenvalues of the spheroidal equation are presented. The results, found using an all orders WKB analysis, include a perturbative/non-perturbati…
