Abstrakt:	Let Dv (z) be the Parabolic Cylinder function. We study the v-zeros of the function v → Dv (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 v-zeros for large positive z. [ABSTRACT FROM AUTHOR]
