On the simpleness of zeros of Stokes multipliers
Abstract
Description
The aim of this paper is to discuss the simpleness of zeros of Stokes multipliers associated with the differential equation $-Φ''(X) + W(X)Φ(X) =0$, where $ W(X) = X^{m} +a_{1}X^{m-1}+... +a_{m}$ is a real monic polynomial. We show that, under a suitable hypothesis on the coefficients $a_k$, all the zeros of the Stokes multipliers are simple.
