Quantum elliptic algebras and double Yangians
L. Frappat
Quantum universal enveloping algebras, quantum elliptic algebras and double (deformed) Yangians provide fundamental algebraic structures relevant for many integrable systems. They…

On the Quasi-Hopf structure of deformed double Yangians
D. Arnaudon, J. Avan, L. Frappat +2
We construct universal twists connecting the centrally extended double Yangian DY(sl(2))_c with deformed double Yangians DY_r(sl(2))_c, thereby establishing the quasi-Hopf structur…
