    • 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 ...
    • Sytongly P-clean Rings and Matrices 

      Chen, H.; Kose, H.; Kurtulmaz, Y. (Elsevier, 2014)
      Abstract. An element of a ring R is strongly P-clean provided that it can be written as the sum of an idempotent and a strongly nilpotent element that commute. A ring R is strongly P-clean in case each of its elements ...
