Subintegrality and ideal class groups of monoid algebras

Md Abu Raihan, Leslie G. Roberts, Husney Parvez Sarwar

$(1)$ Let $M \subset N$ be a commutative cancellative torsion-free and subintegral extension of monoids. Then we prove that in the case of ring extension $A [M] \subset A [N]$ , the two…

Projective modules over Rees-like algebras and its monoid extensions

Chandan Bhaumik, Md Abu Raihan, Husney Parvez Sarwar

Let $A$ be a Rees-like algebra of dimension $d$ and $N$ a commutative partially cancellative torsion-free seminormal monoid. We prove the following results. \begin{enumerate} \item…
