A note on the algebraic engineering of 4D $\mathcal{N}=2$ super Yang-Mills theories

Jean-Emile Bourgine, Kilar Zhang

Some BPS quantities of $\mathcal{N}=1$ 5D quiver gauge theories, like instanton partition functions or qq-characters, can be constructed as algebraic objects of the Ding-Iohara-Mik…
