Note from the Editorial Board

The article M. Aassila “Some results on Heron triangles”, Elem. Math. 56 (2001), 143–146, was received by the editors on April 17, 2001, and acknowledged on April 24, 2001. Following a positive referee’s report, a revised version of the initial manuscript was sub-mitted on July 17, 2001. The manuscript was accepted for publication on September 5, 2001.

In an e-mail of October 27, 2005, and in a detailed letter dated May 26, 2006, Mr. Alpar-Vajk Kramer advised the Editorial Board about the article A.-V. Kramer and F. Luca “Some remarks on Heron triangles”, Acta Acad. Paed. Agriensis, Sec. Math. (N.S.) 27 (2000), 25–38, which had appeared in December 2000. Their manuscript was received by the editors of Acta Acad. Paed. Agriensis on April 12, 2000, and was accepted for publication after a positive referee’s report not later than July 10, 2000.

With regard to the contents, the article of M. Aassila shows strong similiarities to the article of A.-V. Kramer and F. Luca; it even contains several identical formulations. On the other hand, the article of A.-V. Kramer and F. Luca is not mentioned as a reference in M. Aassila’s paper.

By virtue of this evidence a violation of copyrights in the present case cannot be excluded. Unfortunately, the Editorial Board was not able to get a counter-statement from M. Aassila since he could not be reached, neither by ordinary mail nor by e-mail.

The Editorial Board would like to ask the readership of Elemente der Mathematik to take note of this communication and expresses its regrets towards Mr. A.-V. Kramer and Mr. F. Luca in case a violation of copyrights has taken place.
