Phase transition structure and breaking of universal nature of central charge criticality in a Born-Infeld AdS black hole
In this paper we have considered the thermodynamics of a Born-Infeld AdS black hole using
inputs from the dual boundary field theory. Here, we have varied the cosmological constant …
