# Graded Monomial Ordering for $\mathbb{N}$-graded and $\mathbb{N}$-filtered Solvable Polynomial Algebras of $({\cal B},d(~))$-type

## TL;DR

This paper establishes the existence of graded monomial orderings for certain $
$-graded and $
$-filtered solvable polynomial algebras of $({
mf B},d(~))$-type, linking algebraic structure with ordering properties.

## Contribution

It proves that $
$-graded algebras of $({
mf B},d(~))$-type have graded monomial orderings and characterizes $
$-filtered algebras of this type via graded monomial orderings.

## Key findings

- Existence of graded monomial orderings for $
$-graded algebras.
- Characterization of $
$-filtered algebras via monomial orderings.
- Connection between algebraic structure and ordering in solvable polynomial algebras.

## Abstract

Let $K$ be a field, and $A=K[a_1,\ldots ,a_n]$ a solvable polynomial algebra in the sense of [K-RW, {\it J. Symbolic Comput.}, 9(1990), 1--26]. It is shown that if $A$ is an $\mathbb{N}$-graded algebra of $({\cal B},d(~))$-type, then $A$ has a graded monomial ordering $\prec_{gr}$. It is also shown that $A$ is an $\mathbb{N}$-filtered algebra of $({\cal B},d(~))$-type if and only if $A$ has a graded momomial ordering, where ${\cal B}$ is the PBW basis of $A$.
