    Paula Carvalho (Porto), On unit-central rings with stable range one.

  • Abstract:
    In a recent paper Khurana, Marks and Srivastava raised the question whether a ring with stable range 1 is commutative if all its unites are central. We discuss additional conditions under which the question has a positive answer. This is a joint work with C. Lomp and J. Matczuk.
