Universal quadratic forms and Northcott property of infinite number fields

open access: yesJournal of the London Mathematical Society, Volume 110, Issue 5, November 2024.
Abstract We show that if a universal quadratic form exists over an infinite degree, totally real extension of the field of rationals Q$\mathbb {Q}$, then the set of totally positive integers in the extension does not have the Northcott property. In particular, this implies that no universal form exists over the compositum of all totally real Galois ...

CLIFFORD SEMIRINGS AND GENERALIZED CLIFFORD SEMIRINGS

open access: yesTaiwanese Journal of Mathematics, 2005
It is well known that a semigroup $S$ is a Clifford semigroup if and only if $S$ is a strong semilattice of groups. In this paper, we extend this important result from semigroups to semirings by showing that a semiring $S$ is a Clifford semiring if and only if $S$ is a strong distributive lattice of skew-rings.

SIFAT-SIFAT SEMIRING DAN KONSTRUKSINYA [PDF]

open access: yes, 2016
Semiring didefinisikan sebagai himpunan tak kosong dengan dua operasi biner (penjumlahan dan perkalian). Di bawah operasi penjumlahan semiring merupakan monoid komutatif, dan dibawah operasi perkalian merupakan semigrup, serta berlakunya sifat ...

On generalized inverses of regular elements in an arbitrary semiring

open access: yes上海师范大学学报. 自然科学版, 2018
In this paper, we investigate the generalized invertibility for regular elements in an arbitrary semiring. We give some sufficient conditions for the existence of a special kind of {1,2} inverse of a regular element a in an arbitrary semiring and give ...

Embedding semirings in semirings with multiplicative unit [PDF]

open access: yesJournal of the Australian Mathematical Society, 1968
A topological semiring is a system (S, +, ·) where (S, +) and (S, ·) are topological semigroups and · distributes across + as in a ring; that is, for all x, y, z in S, The operations + and · are called addition and multiplication respectively.

Valuations of semirings

open access: yesJournal of Pure and Applied Algebra, 2018
We develop notions of valuations on a semiring, with a view toward extending the classical theory of abstract nonsingular curves and discrete valuation rings to this general algebraic setting; the novelty of our approach lies in the implementation of hyperrings to yield a new definition (\emph{hyperfield valuation}).

On semiring complexity of Schur polynomials [PDF]

open access: yes, 2018
Semiring complexity is the version of arithmetic circuit complexity that allows only two operations: addition and multiplication. We show that semiring complexity of a Schur polynomial {s_\lambda(x_1,\dots,x_k)} labeled by a partition {\lambda=(\lambda_1\
