Retraction Note: Landesman-Lazer type condition for second-order differential equations at resonance with impulsive effects

The Original Article was published on 09 September 2014

This article [1] has been retracted by Professor Ravi P Agarwal, Editor-in-Chief of Advances in Difference Equations.

Following publication of this article, it was brought to the attention of the editorial and publishing staff that this article has substantial overlap with an article by Jin Li, Jianlin Luo, and Zaihong Wang [2], published in November 2014 in Mathematical Modelling and Analysis.

This is a violation of publication ethics which, in accordance with the Committee on Publication Ethics guidelines, warrants a retraction of the article and a notice to this effect to be published in the journal.
