New presentation of the twisted Yangian of type $D$

Shuichi Harako, Mamoru Ueda

We construct a new presentation of the twisted Yangian of type $D$ with a finite number of generators. By using this presentation, we propose a new definition of the twisted affine…

Notes on a homomorphism from the affine Yangian associated with $sl^(n)$ to the affine Yangian associated with $sl (n + 1)$

Mamoru Ueda

In the previous paper, we constructed a homomorphism from the affine Yangian associated with $sl (n)$ to the standard degreewise completion of the affine Yangia…

Affine Yangians and some cosets of non-rectangular $W$ -algebras

Mamoru Ueda

We construct a homomorphism from the affine Yangian associated with $sl (q_{u} - q_{u + 1})$ to the universal enveloping algebra of a $W$ -algebra associated with $\ma…
