Euler’s difference table and the decomposition of tensor powers of the adjoint representation of the $$A_n$$ Lie algebra [PDF]
By using of Euler's difference table, we obtain simple explicit formula for the decomposition of $k$-th tensor power of adjoint representation of $A_n$ Lie algebra at $2 k \le{n+1}$.

The adjoint representation of a Lie algebra and the support of Kostant's weight multiplicity formula [PDF]
Even though weight multiplicity formulas, such as Kostant's formula, exist their computational use is extremely cumbersome. In fact, even in cases when the multiplicity is well understood, the number of terms considered in Kostant's formula is factorial ...

Useful relations among the generators in the defining and adjoint representations of SU(N)
There are numerous relations among the generators in the defining and adjoint representations of SU(N). These include Casimir operators, formulae for traces of products of generators, etc.

Kupershmidt-(dual-)Nijenhuis structures on a Lie algebra with a representation [PDF]
In this paper, first we study infinitesimal deformations of a Lie algebra with a representation and introduce the notion of a Nijenhuis pair, which gives a trivial deformation of a Lie algebra with a representation.

Deformations of the three-dimensional Lie algebra sl(2)
Deformation is one of key questions of the structural theory of algebras over a field. Especially, it plays a important role in the classification of such algebras.

Introduction:: The chemical oscillators are identified as open system that demonstrate periodic changes in the concentration of some reaction species as a result of intricate physico-chemical mechanisms which can lead to bi-stability, the occurrence of ...
