Coproduct for affine Yangians and parabolic induction for rectangular -algebras
Ryosuke Kodera, Mamoru Ueda
We construct algebra homomorphisms from affine Yangians to the current algebras of rectangular -algebras both in type A. The construction is given via the coproduct and the eval…

Twisted Affine Yangian and Rectangular -algebra of type
Mamoru Ueda
We define the twisted affine Yangian of type and construct surjective homomorphisms from twisted affine Yangians of type to the universal enveloping algebra of the rectangu…
