Some properties for ν-zeros of Parabolic Cylinder functions
Résumé
Let D ν (z) be the Parabolic Cylinder function. We study the ν-zeros of the function ν → D ν (z) with respect to the real variable z. We establish a formula for the derivative of a zero and deduce some monotonicity results. Then we also give an asymptotic expansion for ν-zeros for large positive z.
