![]() 3.13 as the referee pointed out), rather it is the S-dual of it. refers to the scipost submission, in the current arxiv version it is the eq. Indeed, in section 3.4.2 the duality frame in which fermionic duality corresponds to Hanany-Witten transitions is not exactly the one in eq. We thank the referee for the well-considered report and for pointing out important typos in section 3.4.2 discussing fermionic dualities. We also provide a string theory derivation of a similar correspondence, proposed by Nekrasov, for rational gl(m|n) spin chains with spins valued in finite-dimensional representations. ![]() ![]() The latter configurations embed the superspin chains into superstring theory. To explain this correspondence, we realize the gauge theories as configurations of branes in string theory and map them by dualities to brane configurations that realize line defects in four-dimensional Chern-Simons theory with gauge group GL(m|n). We present a correspondence between two-dimensional N=(2,2) supersymmetric gauge theories and rational integrable gl(m|n) spin chains with spin variables taking values in Verma modules.
