Lie bialgebra contractions and quantum deformations of quasi-orthogonal algebras
A. Ballesteros, N. A. Gromov, F. J. Herranz +2
Lie bialgebra contractions are introduced and classified. A non-degenerate coboundary bialgebra structure is implemented into all pseudo-orthogonal algebras starting from…
