On a Java library to perform S-expansions of Lie algebras
Carlos Inostroza, Igor Kondrashuk, Nelson Merino +1
The S-expansion method is a generalization of the Inönü-Wigner (IW) contraction that allows to study new non-trivial relations between different Lie algebras. Basically, this metho…
Generating infinite-dimensional algebras from loop algebras by expanding Maurer Cartan forms
R. Caroca, N. Merino, P. Salgado +1
It is shown that the expansion methods developed in refs. arXiv:hep-th/0212347 and arXiv:hep-th/0401033v2 can be generalized so that they permit to study the expansion of algebras…
Bianchi spaces and their 3-dimensional isometries as S-expansions of 2-dimensional isometries
Ricardo Caroca, Igor Kondrashuk, Nelson Merino +1
In this paper we show that some 3-dimensional isometry algebras, specifically those of type I, II, III and V (according Bianchi's classification), can be obtained as expansions of…
S-Expansion of Higher-Order Lie Algebras
Ricardo Caroca, Nelson Merino, Patricio Salgado
By means of a generalization of the S-expansion method we construct a procedure to obtain expanded higher-order Lie algebras. It is shown that the direct product between an Abelian…
