Using WKB analysis, the paper addresses a conjecture of Shapiro and Tater on the similarity between two sets of points in the complex plane; on one side is the set the values of t ∈ C for which the spectrum of the quartic anharmonic oscillator in the complex plane d 2 y d x 2 - x 4 + t x 2 + 2 J x y = Λ y , with certain boundar ...
