Honest errors take down math paper

with one comment

1-s2.0-S0022247X15X00217-cov150hAn incorrect proof has felled a math paper. There’s not too much to say in a straightforward situation like this one, which we’ve seen before — the result of honest errors, not any malfeasance.

Here’s the abstract for “Spectral mapping theorem for generalized Kato spectrum:”

In this paper, we give an affirmative answer to Mbekhta’s conjecture (Mbekhta, 1990) about the pseudo Fredholm operators in Hilbert space. As a consequence, we characterize pseudo Fredholm operators and we prove that the generalized Kato spectrum satisfies the spectral mapping theorem in the Hilbert spaces setting.

The paper — published in the Journal of Mathematical Analysis and Applications — has been cited twice, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:

Oops: Math journal retracts paper accepted by “accidental administrative error”

with 5 comments

jmaaMath journal editors can add — but they can also subtract.

That’s what happened to a 2012 paper in the Journal of Mathematical Analysis and Applications (JMAA), “On the fractional Ostrowski inequality with uncertainty.”

Elsevier editorial system hacked, reviews faked, 11 retractions follow

with 31 comments

elsevierFor several months now, we’ve been reporting on variations on a theme: Authors submitting fake email addresses for potential peer reviewers, to ensure positive reviews. In August, for example, we broke the story of a Hyung-In Moon, who has now retracted 24 papers published by Informa because he managed to do his own peer review.

Now, Retraction Watch has learned that the Elsevier Editorial System (EES) was hacked sometime last month, leading to faked peer reviews and retractions — although the submitting authors don’t seem to have been at fault. As of now, eleven papers by authors in China, India, Iran, and Turkey have been retracted from three journals.

Here’s one of two identical notices that have just run in Optics & Laser Technology, for two unconnected papers: Read the rest of this entry »

Iranian mathematicians latest to have papers retracted for fake email addresses to get better reviews

with 6 comments

It’s tempting to start calling this a trend.

Three Elsevier math journals are among the latest scientific publications to be retracting papers because fake email addresses were used to obtain favorable peer reviews.

The three papers appear in two journals: “On two subclasses of (α,β)-metrics being projectively related,” in the Journal of Geometry and Physics; and “Complex Bogoslovsky Finsler metrics” and “Sasaki–Randers metric in Finsler geometry,” in the Journal of Mathematical Analysis and Applications. All three share authors Akbar Tayebi, of the University of Qom, Iran, and Esmaeil Peyghan, of Arak University, also in Iran.

The notices in the Journal of Mathematical Analysis and Applications read as follows (the EES refers to the Elsevier Editorial System): Read the rest of this entry »
