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…
Einstein and Hilbert: The Creation of General Relativity
Ivan T. Todorov
It took eight years after Einstein announced the basic physical ideas behind the relativistic gravity theory before the proper mathematical formulation of general relativity was ma…
Lectures on Elliptic Functions and Modular Forms in Conformal Field Theory
Nikolay M. Nikolov, Ivan T. Todorov
A concise review of the notions of elliptic functions, modular forms, and theta-functions is provided, devoting most of the paper to applications to Conformal Field Theory (CFT), i…
Global Conformal Invariance and Bilocal Fields with Rational Correlation Functions
Nikolay M. Nikolov, Yassen S. Stanev, Ivan T. Todorov
The singular part of the \textit{operator product expansion} (OPE) of a pair of \textit{globally conformal invariant} (GCI) scalar fields of (integer) dimension can be writ…
Rationality of conformally invariant local correlation functions on compactified Minkowski space
Nikolay M. Nikolov, Ivan T. Todorov
Rationality of the Wightman functions is proven to follow from energy positivity, locality and a natural condition of global conformal invariance (GCI) in any number D of space-tim…
Generalized homologies for the zero modes of the SU(2) WZNW model
Michel Dubois-Violette, Ivan T. Todorov
We generalize the BRS method for the (finite-dimensional) quantum gauge theory involved in the zero modes of the monodromy extended SU(2) WZNW model. The generalization consists of…
