A New Lie Bialgebra Structure on sl(2,1)
Gizem Karaali
Abstract
We describe the Lie bialgebra structure on the Lie superalgebra sl(2,1) related to an r-matrix that cannot be obtained by a Belavin-Drinfeld type construction. This structure makes sl(2,1) into the Drinfeld double of a four-dimensional subalgebra.
