    • 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 ...
    • Very cleanness of generalized matrices 

      Kurtulmaz, Y. (Springer, 2016-01)
      An element a in a ring R is very clean in case there exists an idempotent e 2 R such that ae = ea and either a 􀀀 e or a + e is invertible. An element a in a ring R is very J-clean provided that there exists an idempotent ...
