Description

In holography, or the gauge/gravity correspondence, a local symmetry in the bulk usually translates into a global symmetry on the boundary. In order to introduce dynamical gauge fields in boundary field theory, the method of double-trace deformations has been utilized in various studies. However, this approach may always involve problems of unitarity violation. In this talk, we will review and revisit issues arising when considering double-trace deformation with gauge fields.
