Irreversibility and Higher-spin Conformal Field Theory
I discuss the properties of the central charges c and a for higher-derivative and higher-spin theories (spin 2 included). Ordinary gravity does not admit a straightforward identification of c and a in the trace anomaly, because it is not conformal. On the other hand, higherderivative theories can be conformal, but have negative c and a. A third possibility is to consider higher-spin conformal f...
متن کاملGenus Two Meromorphic Conformal Field Theory
We construct the genus two (or two loop) partition function for meromorphic bosonic conformal field theories. We use a sewing procedure involving two genus one tori by exploiting an explicit relationship between the genus two period matrix and pinching modular parameters. We obtain expressions for the partition function for the chiral bosonic string, even rank lattice theories and self-dual mer...
متن کاملDisordered Systems and Logarithmic Conformal Field Theory
We review a recent development in theoretical understanding of the quenched averaged correlation functions of disordered systems and the logarithmic conformal field theory (LCFT) in d-dimensions. The logarithmic conformal field theory is the generalization of the conformal field theory when the dilatation operator is not diagonal and has the Jordan form. It is discussed that at the random fixed...
متن کاملHigher Powers of White Noise and Conformal Field Theory
Abstract. The Virasoro–Zamolodchikov Lie algebra w∞ has been widely studied in string theory and in conformal field theory. The renormalized higher (≥ 3) powers of quantum white noise (RHPWN) algebra has been recently investigated in quantum probability. We prove that, after introducing a new renormalization technique, the RHPWN Lie algebra can be identified with a second quantization of the w∞...
متن کاملOperads and Conformal Field Theory Lecture 1: Conformal Field Theory
Physicists have developed very advanced methods to compute such integrals. For example, the famous Feynman diagram technique allows us to compute the above integral for a rather particular function S(x), a small perturbation of a positive de nite quadratic form in R . Sometimes, elaborate techniques of physicists to compute simple things nd an amazing application to very general things in mathe...
