Dănuț Marcu

Dănuţ Marcu (born January 11, 1952, Bucharest) is a Romanian mathematician and computer scientist, who received his Ph.D. from the University of Bucharest in 1981. He claims to have authored more than 400 scientific papers.

Marcu is frequently accused of plagiarism. The editors of Studia Universitatis Babeş-Bolyai, Informatica decided to ban Marcu from their journal for this reason, as did the editors of 4OR: A Quarterly Journal of Operations Research and the editors of Geombinatorics. The editors of Geometriae Dedicata state that they suspect Marcu of plagiarism, as he submitted a manuscript which is "more-or-less word for word the same" as a paper by Lindström. Grossman, Kageyama, Pettet, and anonymous reviewers have accused Marcu of plagiarism in MathSciNet reviews. According to the managing editors of Menemui Matematik, Marcu's paper in that journal is a well known result in graph theory, and the paper "should not have been published".
