Lifting defects for nonstable K_0-theory of exchange rings and C*-algebras
Friedrich Wehrung
The assignment (nonstable K_0-theory), that to a ring R associates the monoid V(R) of Murray-von Neumann equivalence classes of idempotent infinite matrices with only finitely nonz…
Semilattices of groups and nonstable K-theory of extended Cuntz limits
Enrique Pardo, Friedrich Wehrung
We give an elementary characterization of those (abelian) semigroups that are direct limits of countable sequences of finite direct products of monoids of the form …
Semilattices of groups and inductive limits of Cuntz algebras
K. R. Goodearl, E. Pardo, F. Wehrung
We characterize, in terms of elementary properties, the abelian monoids which are direct limits of finite direct sums of monoids of the form (where 0 is a new z…
Representations of distributive semilattices in ideal lattices of various algebraic structures
K. R. Goodearl, F. Wehrung
We study the relationships among existing results about representations of distributive semilattices by ideals in dimension groups, von Neumann regular rings, C*-algebras, and comp…
