GRADED HILBERT-SYMBOL EQUIVALENCE OF NUMBER FIELDS
Journal Title: Discussiones Mathematicae - General Algebra and Applications - Year 2015, Vol 35, Issue 1
Abstract
We present a new criterion for the existence of Hilbert-symbol equivalence of two number fields. In principle, we show that the system of local conditions for this equivalence may be expressed in terms of Clifford invariants in place of Hilbert-symbols, shifting the focus from Brauer groups to Brauer-Wall groups.

CODES OVER HYPERFIELDS
In this paper, we define linear codes and cyclic codes over a finite Krasner hyperfield and we characterize these codes by their generator matrices and parity check matrices. We also demonstrate that codes over finite Kr...
SOME HOMOLOGICAL PROPERTIES OF SKEW P BW EXTENSIONS ARISING IN NON-COMMUTATIVE ALGEBRAIC GEOMETRY
In this short paper we study for the skew P BW (Poincar-Birkhoff-Witt) extensions some homological properties arising in non-commutative algebraic geometry, namely, Auslander-Gorenstein regularity, Cohen-Macaulayness and...
ON Γ-SEMIRING WITH IDENTITY
In this paper we study the properties of structures of the semigroup (M, +) and the Γ-semigroup M of Γ-semiring M and regular Γ-semiring M satisfying the identity a + aαb = a or aαb + a = a or a + aαb + b = a or a + 1 =...

LOCAL COHOMOLOGY MODULES AND RELATIVE COHEN-MACAULAYNESS
Let (R, m) denote a commutative Noetherian local ring and let M be a finite R-module. In this paper, we study relative Cohen-Macaulay rings with respect to a proper ideal a of R and give some results on such rings in rel...
