Universal Quantitative Algebra for Fuzzy Relations and Generalised Metric Spaces [PDF]

Logical Methods in Computer Science
We present a generalisation of the theory of quantitative algebras of Mardare, Panangaden and Plotkin where (i) the carriers of quantitative algebras are not restricted to be metric spaces and can be arbitrary fuzzy relations or generalised metric spaces,

More on affine Dynkin quiver Yangians

Journal of High Energy Physics, 2023
We consider the quiver Yangians associated to general affine Dynkin diagrams. Although the quivers are generically not toric, the algebras have some similar structures.

Faithfulf-Free Algebras

Communications in Algebra, 2013
For a polynomial with zero constant term, a semiprime K-algebra R is called faithful f-free if every nonzero ideal of R does not satisfy f. We prove that a semiprime algebra has an essential ideal which is the direct sum of its largest faithful f-free ideal and its largest ideal satisfying the identity f.

A Note on Solvable Polynomial Algebras [PDF]

Computer Science Journal of Moldova, 2014
In terms of their defining relations, solvable polynomial algebras introduced by Kandri-Rody and Weispfenning [J. Symbolic Comput., 9(1990)] are characterized by employing Gr\"obner bases of ideals in free algebras, thereby solvable polynomial ...

Free-field construction of Carrollian W N -algebras

Journal of High Energy Physics
We study Carrollian contractions of W N -algebras from a free-field perspective. Using a contraction of the Miura transformation, we obtain explicit free-field realizations of the resulting Carrollian W N -algebras.

On the structure of Leibniz algebras, whose subalgebras are ideals or core-free

Доповiдi Нацiональної академiї наук України
An algebra L over a field F is said to be a Leibniz algebra (more precisely, a left Leibniz algebra), if it satisfies the Leibniz identity: [[a, b], c] = [a, [b, c]] — [b, [a, c]] for all a, b, c ∈ L. Leibniz algebras are generalizations of Lie algebras.

Hidden role of Maxwell superalgebras in the free differential algebras of D = 4 and D = 11 supergravity

European Physical Journal C: Particles and Fields, 2018
The purpose of this paper is to show that the so-called Maxwell superalgebra in four dimensions, which naturally involves the presence of a nilpotent fermionic generator, can be interpreted as a hidden superalgebra underlying $$\mathcal {N}=1, {\hbox {D}}

Distributive Ockham algebras: free algebras and injectivity [PDF]

Bulletin of the Australian Mathematical Society, 1981
This paper centres around the variety 0 of distributive Ockham algebras, and those subvarieties of 0 which are generated by a single finite subdirectly irreducible algebra A. We use H.A. Priestley's duality for bounded distributive lattices throughout.

Ideal Dasar Prima Dalam Aljabar Atas Suatu Ring Komutatif

Jurnal Fourier, 2018
Definisi ideal dasar dan ideal bebas dalam aljabar bebas atas ring komutatif dengan elemen satuan adalah ekuivalen. Namun, ideal dasar dalam suatu aljabar tak bebas belum tentu merupakan ideal bebas, sementara ideal bebas pasti ideal dasar.
