Retraction Note: Sharp geometrical properties of a-rarefied sets via fixed point index for the Schrödinger operator equations

The Editors-in-Chief have retracted this article [1] because it overlaps significantly with a number of previously published articles from different authors [2-4] and one article by different authors that was simultaneously under consideration with another journal [5]. The article also showed eviden...
