Lax matrices from antidominantly shifted Yangians and quantum affine algebras: A-type

Rouven Frassek, Vasily Pestun, Alexander Tsymbaliuk

We construct a family of $G{L}_n$ rational and trigonometric Lax matrices $T_D(z)$ parametrized by ${\Lambda }^{+}$-valued divisors $D$ on ${\mathbb{P}}^1$. To this end, we study the shifted Drin…
