Non-stable K-theory for Leavitt path algebras
Damon Hay, Marissa Loving, Martin Montgomery +2
We compute the monoid of isomorphism classes of finitely generated projective modules of a Leavitt path algebra over an arbitrary directed graph. Our result generalizes the result…

Square-Free Rings With Local Units
Martin Montgomery
Recently, the author characterized all artinian square-free rings with identity. Here, those results are extended to the setting of rings with local units. We use this characteriza…

Square-Free Rings And Their Automorphism Group
Martin W. Montgomery
Finite-dimensional square-free algebras have been completely characterized by Anderson and D'Ambrosia as certain twisted semigroup algebras over a square-free semigroup S with coef…
