On monoid graded semihereditary rings
Haneen Falah Ghalib Al-Kharsan, Parviz Sahandi, Nematollah Shirmohammadi
In order to study graded left hereditary and left semihereditary rings graded by a cancelation monoid in terms of their modules, we need to revisit graded free, projective, injecti…
A characterization of monoid graded semihereditary rings
Parviz Sahandi, Nematollah Shirmohammadi
Let be a cancellation monoid and be a -graded ring. It is shown that is graded left semihereditary if and only if is graded left coherent a…
On graded going-down domains, II
Parviz Sahandi, Nematollah Shirmohammadi
In this paper we consider the graded going-down property of graded integral domains in pullbacks. It then enables us to give original examples of these domains.
The space of homogeneous preserving semistar operations on graded domains
Parviz Sahandi
Let be a graded integral domain. In this paper we study the space of homogeneous preserving semistar operations on . We show if is a homogeneous…
On a particular subspace of homogeneous preserving star operations
Parviz Sahandi
Let be a torsionless commutative cancellative monoid, be a -graded integral domain. In this note we show that each homogeneous star operation $\sta…
On graded Going down domains
Parviz Sahandi, Nematollah Shirmohammadi
Let be a torsionless commutative cancellative monoid and be a -graded integral domain. In this paper, we introduce the notion of graded going-down…
