Suggestion of a definition of the twisted affine Yangian of type
Mamoru Ueda
We suggest a definition of the 1-parameter twisted affine Yangian and the 2-parameter twisted affine Yangian $TY_{\hbar,\ve}(\widehat{\math…

New presentation of the twisted Yangian of type
Shuichi Harako, Mamoru Ueda
We construct a new presentation of the twisted Yangian of type with a finite number of generators. By using this presentation, we propose a new definition of the twisted affine…
