    • Factorizations of matrices over projective-free Rings 

      Chen, H.; Kose, H.; Kurtulmaz, Y. (World Scientific Publishing Co. Pte Ltd, 2016)
      An element of a ring R is called strongly J#-clean provided that it can be written as the sum of an idempotent and an element in J#(R) that commute. In this paper, we characterize the strong J#-cleanness of matrices over ...
    • Strongly j-clean skew triangular matrix rings 

      Kurtulmaz, Y. (Universitatea "Alexandru Ioan Cuza" din Iasi * Facultatea de Matematica,"Alexandru Ioan Cuza" University of Iasi, Faculty of Mathematics, 2016-02-06)
      Let R be an arbitrary ring with identity. An element a 2 R is strongly J-clean if there exist an idempotent e 2 R and element w 2 J(R) such that a = e + w and ew = ew. A ring R is strongly J-clean in case every element ...
