Retraction Note: Levin’s type boundary behaviors for functions harmonic and admitting certain lower bounds

Abstract

The Editors-in-Chief have retracted this article [1] because it significantly overlaps with a previously published article by Pang et al. [2]. The article also shows evidence of authorship manipulation. The identity of the corresponding author could not be verified; the University of Ioannina have confirmed that Mohamed Vetro has not been affiliated with their institution. The authors have not responded to correspondence regarding this retraction.
