A not so simple local multiplier algebra
Pere Ara, Martin Mathieu
We construct an AF-algebra such that its local multiplier algebra does not agree with , thus answering a question raised…
Nonstable -theory for graph algebras
P. Ara, M. A. Moreno, E. Pardo
We compute the monoid of isomorphism classes of finitely generated projective modules over certain graph algebras , 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 in a unital C*-algebra has K-theoretic stable rank greater than or equal to the stable rank of . (Here is a proje…
Fractional skew monoid rings
P. Ara, M. A. Gonzalez-Barroso, K. R. Goodearl +1
Given an action of a monoid on a ring by ring endomorphisms, and an Ore subset of , a general construction of a fractional skew monoid ring is g…
of purely infinite simple regular rings
P. Ara, K. R. Goodearl, E. Pardo
We extend the notion of a purely infinite simple C*-algebra to the context of unital rings, and we study its basic properties, specially those related to K-Theory. For instance, if…
Extensions and Pullbacks in QB-rings
Pere Ara, Gert K. Pedersen, Francesc Perera
We prove a new extension result for rings that allows us to examine extensions of rings where the ideal is purely infinite and simple. We then use this result to explore vario…
