چکیده
Boundary conformal field theory (BCFT) is simply the study of conformal field theory (CFT) in domains with a boundary. It gains its significance because, in some ways, it is mathematically simpler: the algebraic and geometric structures of CFT appear in a more straightforward manner; and because it has important applications: in string theory in the physics of open strings and D-branes, and in condensed matter physics in boundary critical behavior and quantum impurity models.

UH - 08 / 02 Boundary States in c = − 2 Logarithmic Conformal Field Theory
Starting from first principles, a constructive method is presented to obtain boundary states in conformal field theory. It is demonstrated that this method is well suited to compute the boundary states of logarithmic conformal field theories. By studying the logarithmic conformal field theory with central charge c = −2 in detail, we show that our method leads to consistent results. In particula...

متن کاملTwo-Point Functions and Boundary States in Boundary Logarithmic Conformal Field Theories
Amongst conformal field theories, there exist logarithmic conformal field theories such as cp,1 models, various WZNW models, and a large variety of statistical models. It is well known that these theories generally contain a Jordan cell structure, which is a reducible but indecomposable representation. Our main aim in this thesis is to address the results and prospects of boundary logarithmic c...
