    • 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 clean matrices over power series 

      Chen, H.; Kose, H.; Kurtulmaz, Y. (Kyungpook National University, 2016)
      An n × n matrix A over a commutative ring is strongly clean provided that it can be written as the sum of an idempotent matrix and an invertible matrix that commute. Let R be an arbitrary commutative ring, and let A(x) ∈ ...
