Conformal Field Theory, Boundary Conditions and Applications to String Theory
This is an introduction to two-dimensional conformal field theory and its applications in string theory. Modern concepts of conformal field theory are explained, and it is outlined how they are used in recent studies of D-branes in the strong curvature regime by means of CFT on surfaces with boundary.

I give an elementary introduction to conformal field theory and its applications to string theory.
متن کاملHolography from Conformal Field Theory
The locality of bulk physics at distances below the AdS length scale is one of the remarkable aspects of AdS/CFT duality, and one of the least tested. It requires that the AdS radius be large compared to the Planck length and the string length. In the CFT this implies a large-N expansion and a gap in the spectum of anomalous dimensions. We conjecture that the implication also runs in the other ...
متن کاملBorn-Infeld String as a Boundary Conformal Field Theory
Solutions of Born-Infeld theory, representing strings extending from a Dirichlet p-brane, are also solutions of the higher derivative generalization of the Born-Infeld equations defining an exact open string vacuum configuration.
متن کاملHeterotic String Conformal Field Theory And A-D-E Singularities
We analyze the behavior of the heterotic string near an A-D-E singularity without small instantons. This problem is governed by a strongly coupled worldsheet conformal field theory, which, by a combination of O(α′) corrections and worldsheet instantons, smooths out the singularities present in the classical geometry.
