Contractions d'algèbres de Jordan en dimension 2 [Contractions of Jordan algebras in dimension 2]
J. M. Ancochea Bermudez, R. Campoamor-Stursberg, L. Garcia Vergnolle +1
We determine the isomorphism classes of Jordan algebras in dimension two over the field of real numbers. Using techniques of non-standard analysis we study the properties of the va…
Generalized Casimir invariants of six dimensional solvable real Lie algebras with five dimensional nilradical
Rutwig Campoamor-Stursberg
We finish the determination of the invariants of the coadjoint representation of six dimensional real Lie algebras, by determining a fundamental set of invariants for the 99 isomor…
Contractions and generalized Casimir invariants
Rutwig Campoamor-Stursberg
We prove that if is a contraction of a Lie algebra then the number of functionally independent invariants of is at least that of…
Simple completable contractions of nilpotent Lie algebras
Rutwig Campoamor-Stursberg
We study a certain class of non-maximal rank contractions of the nilpotent Lie algebra and show that these contractions are completable Lie algebras. As a consequenc…
