On Serre dimension of monoid algebras and Segre extensions

Manoj Kumar Keshari, Maria Ann Mathew

Let $R$ be a commutative noetherian ring of dimension $d$ and $M$ be a commutative $,$ cancellative $,$ torsion-free monoid of rank $r$ . Then $S$ -$dim(R[M]) \leq max\{1, dim(R[M])-1…

Unimodular rows over monoid extensions of overrings of polynomial rings

Maria A. Mathew, Manoj K. Keshari

Let $R$ be a commutative Noetherian ring of dimension $d$ and $M$ a commutative cancellative torsion-free seminormal monoid. Then (1) Let $A$ be a ring of type $R [d, m, n]$ and $P$ b…
