An Infinite Set of Ward Identities for Adiabatic Modes in Cosmology
, 2014
"... We show that the correlation functions of any singlefield cosmological model with constant growingmodes are constrained by an infinite number of novel consistency relations, which relate N + 1point correlation functions with a softmomentum scalar or tensor mode to a symmetry transformation on N ..."

point correlation functions of hardmomentum modes. We derive these consistency relations from Ward identities for an infinite tower of nonlinearly realized global symmetries governing scalar and tensor perturbations. These symmetries can be labeled by an integer n. At each order n, the consistency relations
Ward Identities of W∞ Symmetry in Liouville Theory

"... We investigate the Ward identities of the W ∞ symmetry in the Liouville theory coupled to the (p, q) conformal matter. The correlation functions are defined by applying the analytic continuation procedure for the matter sector as well as the Liouville one. We then find that the Ward identities are e ..."

"... We present the method, based on the use of the broken conformal Ward identities, for the calculation of the anomalous dimensions of conformal operators beyond the leading order of perturbation theory. By means of this technique we find the complete set of twoloop corrections to the nondiagonal elem ..."

Duality between Wilson Loops and Scattering Amplitudes ∗
, 810
"... We summarise the status of an intriguing new duality between planar maximally helicity violating scattering amplitudes and lightlike Wilson loops in N = 4 super YangMills. In particular, we focus on the role played by (dual) conformal symmetry, which is made predictive by deriving anomalous confor ..."

Tachyon potentials, star products and universality
 JHEP 0109 (2001) 038 [arXiv:hepth/0006240
"... We develop an efficient recursive method to evaluate the tachyon potential using the relevant universal subalgebra of the open string star algebra. This method, using offshell versions of Virasoro Ward identities, avoids explicit computation of conformal transformations of operators and does not re ..."

A social identity theory of leadership.
 Personality and Social Psychology Review,
, 2001
"... A social identity theory of leadership is described that views leadership as a group process generated by social categorization and prototypebased depersonalization processes associated with social identity. Group identification, as selfcategorization, constructs an intragroup prototypicality gra ..."

The representation of the algebra Upq(su(1, 1)) on the space of quasiprimary fields is given. The (p, q)deformed Ward identities of conformal field theory are defined. The ..."

"... We extend and develop a method for perturbative calculations of anomalous dimensions and mixing matrices of leading twist conformal primary operators in conformal field theories. Such operators lie on the unitarity bound and hence are conserved (irreducible) in the free theory. The technique relies ..."

compare these results to another method based on anomalous conformal Ward identities and constraints from the conformal algebra. It also permits to gain a perturbative order in computations of mixing matrices. We show the complete equivalence of both approaches.
