For example: Keskin, A .; Noiri, T. and Yuksel S. Idealization of decomposition theorem, Acta Math. Hung., 102 (4) (2004), 269–277.

• The bibliographic references of books must include: Author (s) (in upper and lower case), title, publisher, place of publication, year, pages. For example: Kuratowski, K. Topology, Vol. 1, Academic Press, New York, 1966.
