Novel Free Differential Algebras for Supergravity

open access: yesUniverse, 2023
We develop the theory of Free Integro-Differential Algebras (FIDA) extending the powerful technique of Free Differential Algebras constructed by D. Sullivan. We extend the analysis beyond the superforms to integral- and pseudo-forms used in supergeometry.

An overview of free nilpotent Lie algebras [PDF]

open access: yes, 2011
summary:Any nilpotent Lie algebra is a quotient of a free nilpotent Lie algebra of the same nilindex and type. In this paper we review some nice features of the class of free nilpotent Lie algebras.

Equivalential algebras with conjunction on the regular elements

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2021
We introduce the definition of the three-element equivalential algebra R with conjunction on the regular elements. We study the variety generated by R and prove the Representation Theorem.

On extensions of gl m n ⏜ $$ \mathfrak{gl}\widehat{\left(\left.m\right|n\right)} $$ Kac-Moody algebras and Calabi-Yau singularities

open access: yesJournal of High Energy Physics, 2020
We discuss a class of vertex operator algebras W m n × ∞ $$ {\mathcal{W}}_{\left.m\right|n\kern0.33em \times \kern0.33em \infty } $$ generated by a super- matrix of fields for each integral spin 1, 2, 3, . . . .

On Free Pseudo-Product Fundamental Graded Lie Algebras

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
In this paper we first state the classification of the prolongations of complex free fundamental graded Lie algebras. Next we introduce the notion of free pseudo-product fundamental graded Lie algebras and study the prolongations of complex free pseudo ...

Free Algebras Over a Poset in Varieties of Łukasiewicz–Moisil Algebras

open access: yesDemonstratio Mathematica, 2015
A general construction of the free algebra over a poset in varieties finitely generated is given in [8]. In this paper, we apply this to the varieties of Łukasiewicz-Moisil algebras, giving a detailed description of the free algebra over a finite poset ...

Bases as Coalgebras [PDF]

open access: yesLogical Methods in Computer Science, 2013
The free algebra adjunction, between the category of algebras of a monad and the underlying category, induces a comonad on the category of algebras. The coalgebras of this comonad are the topic of study in this paper (following earlier work).

The Algebraic Sets of Broad Algebras

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
The paper is devoted to the questions of algebraic geometry of universal algebras, more precisely, to the structures of algebraic sets of this algebras. It is introduced the concept of broad universal algebra.

Free Semigroupoid Algebras

open access: yes, 2003
Every countable directed graph generates a Fock space Hilbert space and a family of partial isometries. These operators also arise from the left regular representations of free semigroupoids derived from directed graphs. We develop a structure theory for the weak operator topology closed algebras generated by these representations, which we call free ...
