Retracted: Universality of affine semi-groups on supercyclicity of the sequence operators

Abstract

This article [1] has been retracted due to an accusation of plagiarism. It was found to contain a substantial amount of contents from a previously published article "S. Shkarin, On supercyclicity of operators from a supercyclic semigroup, J. Math. Anal. Appl. 382 (2011), 516–522". Although this article was cited as reference 9 in [1], it is believed that sufficient evidence exists to support this accusation. We apologize to the readers that this was not detected before publication.
