*“QFT in AdS as a set of ODEs"*
*
*

_Abstract_

Correlation functions of local operators in Quantum Field Theory (QFT) 
in Anti-de Sitter (AdS) space can be fully characterised by the QFT 
data: scaling dimensions of boundary operators, boundary Operator 
Product Expansion (OPE) coefficients, and Boundary Operator Expansion 
(BOE) coefficients  for each bulk operator.
In this talk I will focus on 2D QFTs and present a set of universal 
first order Ordinary Differential Equations (ODEs) that encode the 
variation of the QFT data under an infinitesimal change of a bulk 
relevant coupling. In principle, these ODEs can be used to follow a 
Renormalisation Group (RG) flow starting from a solvable QFT into a 
strongly coupled phase and to the flat space limit. I will explain the 
derivation of the ODEs and show explicit numerical tests in the free 
scalar theory.
