Euclidean AdS is equivalent to the half-space by a Weyl transformation, providing a convenient setup for studying boundary CFT and interface CFT (the latter after performing the folding trick). I will discuss boundary criticality of the Wilson-Fisher (WF) CFT and interface criticality of the Gross-Neveu-Yukawa (GNY) CFT in this setup. In the first half of the talk, I will present an epsilon-expansion result for the boundary central charge of the normal boundary transition of the WF CFT, and compare it with a recent fuzzy sphere result. In the second part, I will present a novel surface fixed point in the 3d GNY model using large N arguments.
