Weight module classifications for Bershadsky--Polyakov algebras

open access: yes, 2023
The Bershadsky--Polyakov algebras are the subregular quantum hamiltonian reductions of the affine vertex operator algebras associated with $\mathfrak{sl}_3$.

Derivations of some classes of Leibniz algebras [PDF]

open access: yes, 2013
Let L be an algebra over a field K. It is called a Leibniz algebra if its the bilinear binary operation [ ; ] satisfies the following Leibniz identity: (x, [y, z]) = ([x, y]), z – ([x, z]), y , ∀ x, y, z ∈ L.

Kappa Coefficients for Circular Classifications [PDF]

open access: yes, 2016
Circular classifications are classification scales with categories that exhibit a certain periodicity. Since linear scales have endpoints, the standard weighted kappas used for linear scales are not appropriate for analyzing agreement between two ...

Relative positions of matroid algebras.

open access: yes, 1999
A classification is given for regular positions DDD of Jones index 4 where -- EQUATION OMITTED -- is an even matroid algebra and where the individual summands have index 2.

Quantum family algebras [PDF]

open access: yes, 2020
. Recently, A. A. Kirillov introduced an important notion of classical and quantum family algebras. Here the criterion of commutativity is given. The quantum eigenvalues of sl 2 ðCÞ are computed. Mathematics Subject Classifications (2000) . Primary 15A30,

Quiver representations for Leavitt Path algebras as talented monoid classification detour. [PDF]

open access: yes
There is a correspondence between quiver representations and path algebras. In this talk, we will see Leavitt Path algebras as a special case for such representation and how it will take a role in its classifications in relation to classifications in ...

Computational methods for nilsoliton metric Lie algebras I

open access: yes, 2013
We introduce a computational method for classifying Lie algebras admitting a nilsoliton inner product in a large subclass of the set of all nilpotent Lie algebras.

Classification methods for primitive table algebras of dimension 4

open access: yes, 2008
Table algebras and C-algebras are algebras over the complex numbers with a distinguished basis that satisfies certain axioms. In particular, the structure constants are real numbers. Classification theorems are proved for various types of 4-dimensional C-

Category kappas for agreement between fuzzy classifications [PDF]

open access: yes, 2016
The kappa statistic is a widely used as a measure for quantifying agreement between two nominal classifications. The statistic has been extended to the case of two normalized fuzzy classifications.

Homology for operator algebras IV: n the regular classifications of limits of 4-cycle algebras.

open access: yes, 1997
A 4-cycle algebra is a finite-dimensional digraph algebra (CSL algebra) whose reduced digraph is a 4-cycle. A rigid embedding between such algebras is a direct sum of certain nondegenerate multiplicity one star-extendible embeddings.
