An infinite analogue of rings with stable rank one

Pere Ara, Gert K. Pedersen, Francesc Perera

Replacing invertibility with quasi-invertibility in Bass' first stable range condition we discover a new class of rings, the QB-rings. These constitute a considerable enlargement o…

$K_{1}$ of separative exchange rings and C*-algebras with real rank zero

P. Ara, K. R. Goodearl, K. C. O'Meara +1

For any (unital) exchange ring $R$ whose finitely generated projective modules satisfy the separative cancellation property ( $A \oplus A ≅ A \oplus B ≅ B \oplus B$ implies $A\co…
