A signature-based algorithm for computing Gröbner-Shirshov bases in skew solvable polynomial rings
Published 2015-05-01“…Signature-based algorithms are efficient algorithms for computing Gröbner-Shirshov bases in commutative polynomial rings, and some noncommutative rings. In this paper, we first define skew solvable polynomial rings, which are generalizations of solvable polynomial algebras and (skew) PBW extensions. …”

Homogenized skew PBW extensions
Published 2022-12-01“…Abstract In this paper, we provide a new and more general filtration to the family of noncommutative rings known as skew PBW extensions. We introduce the notion of $$\sigma $$ σ -filtered skew PBW extension and study some homological properties of these algebras. …”

Equalizing ideal for integer-valued polynomials over the upper triangular matrix ring
Published 2023-08-01“…Recently, integer-valued polynomials have been considered over some noncommutative rings (see for examples [3, 5, 6, 10]. In [1], Cahen and Chabert introduced the notion of equalizing ideal for a maximal ideal of $D$. …”
