A bstract We introduce a formalism for describing holomorphic blocks of 3 d quiver gauge theories using networks Ding-Iohara-Miki algebra intertwiners. Our approach is very direct and gives an explicit identification the with Dotsenko-Fateev type integrals q -deformed W -algebras. also explain how corresponding to Dynkin diagrams superalgebras arise, write down partition functions -algebras, co...
