RT Journal Article T1 Non-solvable contractions of semisimple Lie algebras in low dimension A1 Campoamor Stursberg, Otto-Rudwig AB The problem of non-solvable contractions of Lie algebras is analyzed. By means of a stability theorem, the problem is shown to be deeply related to the embeddings among semisimple Lie algebras and the resulting branching rules for representations. With this procedure, we determine all deformations of indecomposable Lie algebras having a nontrivial Levi decomposition onto semisimple Lie algebras of dimension n ≤ 8, and obtain the non-solvable contractions of the latter class of algebras PB IOP Publishing SN 0305-4470 YR 2007 FD 2007 LK https://hdl.handle.net/20.500.14352/50649 UL https://hdl.handle.net/20.500.14352/50649 LA eng NO Ministerio de Educación, Formación Profesional y Deportes (España) DS Docta Complutense RD 19 abr 2025
