Infinite dimensional Lie algebras in 4D conformal quantum field theory
B. Bakalov, N. M. Nikolov, K. -H. Rehren +1
The concept of global conformal invariance (GCI) opens the way of applying algebraic techniques, developed in the context of 2-dimensional chiral conformal field theory, to a highe…
Harmonic bilocal fields generated by globally conformal invariant scalar fields
Nikolay M. Nikolov, Karl-Henning Rehren, Ivan Todorov
The twist two contribution in the operator product expansion of phi_1(x_1) phi_2(x_2) for a pair of globally conformal invariant, scalar fields of equal scaling dimension d in four…
Partial wave expansion and Wightman positivity in conformal field theory
N. M. Nikolov, K. -H. Rehren, I. T. Todorov
A new method for computing exact conformal partial wave expansions is developed and applied to approach the problem of Hilbert space (Wightman) positivity in a non-perturbative fou…
QFT Lectures on AdS-CFT
Karl-Henning Rehren
It is discussed to which extent the AdS-CFT correspondence is compatible with fundamental requirements in quantum field theory.
A Proof of the AdS-CFT Correspondence
K. -H. Rehren
The AdS-CFT correspondence is established as a re-assignment of localization to the observables which is consistent with locality and covariance.
Bounded Bose fields
K. -H. Rehren
Examples for bounded Bose fields in two dimensions are presented.
