Twisted holography of defect fusions
arXiv:2103.00963 · doi:10.21468/SciPostPhys.10.5.105
Abstract
In the twisted M-theory setting, various types of fusion of M2 and M5 branes induce coproducts between the algebra of operators on M2 branes and the algebra of operators on M5 branes. By doing a perturbative computation in the gravity side, which is captured by the 5d topological holomorphic Chern-Simons theory, we reproduce the non-perturbative coproducts.
