On the algorithm to find S-related Lie algebras
Carlos Inostroza, Igor Kondrashuk, Nelson Merino +1
In this article we describe the Java library that we have recently constructed to automatize the S-expansion method, a powerful mathematical technique allowing to relate different…
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…
The Segre embedding of the quantum conformal superspace
R. Fioresi, E. Latini, M. A. Lledo +1
In this paper study the quantum deformation of the superflag Fl(2|0, 2|1,4|1), and its big cell, describing the complex conformal and Minkowski superspaces respectively. In particu…
A Java library to perform S-expansions of Lie algebras
C. Inostroza, I. Kondrashuk, N. Merino +1
The contraction method is a procedure that allows to establish non-trivial relations between Lie algebras and has had succesful applications in both mathematics and theoretical phy…
General properties of the expansion methods of Lie algebras
Laura Andrianopoli, Nelson Merino, Felip Nadal +1
The study of the relation between Lie algebras and groups, and especially the derivation of new algebras from them, is a problem of great interest in mathematics and physics, becau…
Quadratic deformation of Minkowski space
D. Cervantes, R. Fioresi, M. A. Lledo +1
We present a deformation of the Minkowski space as embedded into the conformal space (in the formalism of twistors) based in the quantum versions of the corresponding kinematic gro…
Quantum twistors
D. Cervantes, R. Fioresi, M. A. Lledó +1
We compute explicitly a star product on the Minkowski space whose Poisson bracket is quadratic. This star product corresponds to a deformation of the conformal spacetime, whose big…
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…
