Vertex Representations for Yangians of Kac-Moody algebras

Nicolas Guay, Vidas Regelskis, Curtis Wendlandt

Using vertex operators, we build representations of the Yangian of a simply laced Kac-Moody algebra and of its double. As a corollary, we prove the PBW property for simply laced af…

Twisted Yangians of small rank

Nicolas Guay, Vidas Regelskis, Curtis Wendlandt

We study quantized enveloping algebras called twisted Yangians associated with the symmetric pairs of types CI, BDI and DIII (in Cartan's classification) when the rank is small. We…
