Automorphisms of sl(2) and dynamical r-matrices
Abstract
Two outer automorphisms of infinite-dimensional representations of sl(2) algebra are considered. The similar constructions for the loop algebras and yangians are presented. The corresponding linear and quadratic R-brackets include the dynamical r-matrices.
