More on affine Dynkin quiver Yangians

We consider the quiver Yangians associated to general affine Dynkin diagrams. Although the quivers are generically not toric, the algebras have some similar structures. The odd reflections of the affine Dynkin diagrams should correspond to Seiberg duality of the quivers, and we investigate the relations of the dual quiver Yangians. We also mention the construction of the twisted quiver Yangians. It is conjectured that the truncations of the (twisted) quiver Yangians can give rise to certain ?�-algebras. Incidentally, we give the screening currents of the ?�-algebras in terms of the free field realization in the case of generalized conifolds. Moreover, we discuss the toroidal and elliptic algebras for any general quivers.

Automated summary

This article deals with quiver Yangians associated with general affine Dynkin diagrams. Although the quivers are not toric in general, the algebras exhibit similar structures. The odd reflections of the affine Dynkin diagrams are expected to correspond to Seiberg duality of the quivers, and the relationships of dual quiver Yangians are investigated. The construction of twisted quiver Yangians is also discussed. It is conjectured that truncations of the (twisted) quiver Yangians yield certain ?�-algebras. Additionally, the screening currents of the ?�-algebras are presented in terms of free field realization in the case of generalized conifolds. Furthermore, toroidal and elliptic algebras for general quivers are explored.
