For a Dynkin quiverof typeand a sumof simple roots, we construct a bimodule over the quantum loop algebra and the quiver Hecke algebra of the corresponding type via equivariant-theory, imitating Ginzburg–Reshetikhin–Vasserot’s geometric realization of the quantum affine Schur–Weyl duality. Our construction is based on Hernandez–Leclerc’s isomorphism between a certain graded quiver variety and the space of representations of the quiverof dimension vector. We identify the functor induced from our bimodule with Kang–Kashiwara–Kim’s generalized quantum affine Schur–Weyl duality functor. As a by-product, we verify a conjecture by Kang–Kashiwara–Kim on the simpleness of some poles of normalized-matrices for any quiverof type.
