Dirichlet, Neumann, Mixed and self-dual holography: (self-dual) Yang--Mills theory II

We consider Yang–Mills, Chalmers–Siegel and self-dual Yang–Mills (SDYM) theories within AdS/CFT correspondence. Bulk-to-bulk and boundary-to-bulk propagators are derived in various gauges and for Dirichlet, Neumann, mixed and self-dual boundary conditions. Three- and four-point holographic correlators are computed in the three theories to establish the relation between the observables thereof. This is a companion paper to [arXiv:2602.21658].
