Nonstable $K$ -theory for graph algebras

P. Ara, M. A. Moreno, E. Pardo

We compute the monoid $V (L_{K} (E))$ of isomorphism classes of finitely generated projective modules over certain graph algebras $L_{K} (E)$ , and we show that this monoid satisfies the r…

Stable rank of corner rings

P. Ara, K. R. Goodearl

B. Blackadar recently proved that any full corner $p A p$ in a unital C*-algebra $A$ has K-theoretic stable rank greater than or equal to the stable rank of $A$ . (Here $p$ is a proje…

Fractional skew monoid rings

P. Ara, M. A. Gonzalez-Barroso, K. R. Goodearl +1

Given an action of a monoid $T$ on a ring $A$ by ring endomorphisms, and an Ore subset $S$ of $T$ , a general construction of a fractional skew monoid ring $S^{op} * A * T$ is g…
