                                      Malcolmson semigroup

                                      Abstract: The Cuntz semigroup and dimension functions for C*-algebras were introduced by Cuntz as means to study simple C*-algebras. From the
                                      analogy between dimension functions and Sylvester matrix rank functions, we introduce the matrix Malcolmson semigroup for unital rings, as an
                                      algebraic counterpart of the Cuntz semigroup. In this talk, we will talk about this semigroup and a module version of it. This is a joint work with
                                      Hanfeng Li.
