Hanany-Witten brane crossing and Ding-Iohara-Miki algebra

Abstract: We further develop the correspondence between representations of Ding-Iohara-Miki (DIM) algebra and Type IIB branes. In particular we explicitly compute the Hanany-Witten type 5-brane crossing operator which plays the role of the $R$-matrix and has interesting combinatorial properties. We explore the corresponding lattice integrable models and notice a possible connection with statistics of plane partitions.
