Correlation Functions and AdS/LCFT Correspondence
Correlation functions of Logarithmic conformal field theory is investigated
using the ADS/CFT correspondence and a novel method based on nilpotent weights
and 'super fields'. Adding an specific form of interaction, we introduce a
perturbative method to calculate the correlation functions.Comment: 11 pages, 4 figure
On the AdS/CFT Correspondence and Logarithmic Operator
Logarithmic conformal field theory is investigated using the AdS/CFT
correspondence and a novel method based on nilpotent weights. Using this device
we add ghost fermions and point to a BRST invariance of the theory.Comment: 8 Pages, Typos corrected, references added changes in the content of

Critical Factors in Competitive Advantage of Islamic Banking
This research focuses on determining the impact of service quality, customer satisfaction, and loyalty programs on customersâ loyalty in the banking sector of Malaysia. It is obvious that customers are important stakeholders in organisations, and their satisfaction is a priority to the management. Customer satisfaction has been a subject of great interest to organisations and researchers alike. In recent years, organisations are obliged to render additional services on top of their offers. The quality of service has become an aspect of customer satisfaction
Avalanche frontiers in dissipative abelian sandpile model as off-critical SLE(2)
Avalanche frontiers in Abelian Sandpile Model (ASM) are random simple curves
whose continuum limit is known to be a Schramm-Loewner Evolution (SLE) with
diffusivity parameter . In this paper we consider the dissipative
ASM and study the statistics of the avalanche and wave frontiers for various
rates of dissipation. We examine the scaling behavior of a number of functions
such as the correlation length, the exponent of distribution function of loop
lengths and gyration radius defined for waves and avalanches. We find that they
do scale with the rate of dissipation. Two significant length scales are
observed. For length scales much smaller than the correlation length, these
curves show properties close to the critical curves and the corresponding
diffusivity parameter is nearly the same as the critical limit. We interpret
this as the ultra violet (UV) limit where corresponding to .
For length scales much larger than the correlation length we find that the
avalanche frontiers tend to Self-Avoiding Walk, the corresponding driving
function is proportional to the Brownian motion with the diffusion parameter
corresponding to a field theory with . This is the infra
red (IR) limit. Correspondingly the central charge decreases from the IR to the
UV point.Comment: 11 Pages, 6 Figure
Higher Order and boundary Scaling Fields in the Abelian Sandpile Model
The Abelian Sandpile Model (ASM) is a paradigm of self-organized criticality
(SOC) which is related to conformal field theory. The conformal fields
corresponding to some height clusters have been suggested before. Here we
derive the first corrections to such fields, in a field theoretical approach,
when the lattice parameter is non-vanishing and consider them in the presence
of a boundary.Comment: 7 pages, no figure
