Notice of Retraction: “Growth property at infinity of the maximum modulus with respect to the Schrödinger operator”

In this paper, we consider the growth property at infinity of the maximum modulus with respect to the Schrodinger operator in a cone, which supplement Phragmen–Lindelof theorems for subfunctions obtained by Qiao and Pan (Generalization of the Phragmen–Lindelof theorems for subfunctions, Internat. J. Math. 24 (2013) Article ID: 1350062).
