In Apologiam
Publicly available scientific knowledge results from the accumulated work of all researchers sharing their ideas and results with others. This edifice is enormous, but it is made up of small units each one of us contributes. To fit one new piece into the knowledge base, two main conditions must be fulfilled. First, the contribution must be new, and second, it must be evaluated by peer review. The novelty is mainly the responsibility of the contributor. The state-of-the-art must be known and the added value must be clearly presented. Evaluation is in the hands of editors. They rely on a large team of experts who assess the proposal, check the novelty, possibly suggest improvements, or reject. The whole process is based on mutual trust and confidence. Whenever it is broken, the case does not help the offender at all.

RETRACTED: An algorithm for stability of discrete-time interval matrices

Reason: It is clear for all to see that this article is a close copy of the earlier article: A. Bulgak: Checking a practical asymptotic stability of an interval matrix. Selcuk Journal of Applied Mathematics 2 (2001) 17–26. Although this article references A. Bulgak's article as Ref. [5], large passages are copied word-for-word, without explanation of what is known and what is new. This is a clear violation of the rules of practice in scientific work, generally accepted by the scientific community.

It is hence my editorial duty to herewith offer, together with our reviewers, our sincerest apologies to Dr. A. Bulgak, to our readership and to the mathematical community at large, for not having detected this most unfortunate case of copying/plagiarism during the review process.

RETRACTED: On stability of discrete-time interval matrices

Reason: It is clear for all to see that this article is a close copy of the earlier article: H. Bulgak: Pseudoeigenvalues, spectral portrait of a matrix and their connections with different criteria of Stability. In: Error Control and Adaptivity in Scientific Computing; H. Bulgak and C. Zenger, Eds., Kluwer (1999) 95–124. Large passages are copied word-for-word, without explanation of what is known and what is new. This is a clear violation of the rules of practice in scientific work, generally accepted by the scientific community.

It is hence my editorial duty to herewith offer, together with our reviewers, our sincerest apologies to Prof. H. Bulgak, to our readership and to the mathematical community at large, for not having detected this most unfortunate case of copying/plagiarism during the review process.

Results of this paper form a part of the Ph.D. Thesis [1] written by Yamac at Selcuk University under the direction of Bozkurt.
