Topological and conformal field theory as Frobenius algebras
Two-dimensional conformal field theory (CFT) can be defined through its correlation functions. These must satisfy certain consistency conditions which arise from the cutting of world sheets along
Category theory for conformal boundary conditions
We study properties of the category of modules of an algebra object A in a tensor category C. We show that the module category inherits various structures from C, provided that A is a Frobenius
Crosscaps, boundaries and T-duality
Conformal correlation functions, Frobenius algebras and triangulations
We formulate two-dimensional rational conformal field theory as a natural generalization of two-dimensional lattice topological field theory. To this end we lift various structures from complex
Orbifold analysis of broken bulk symmetries
Abstract In two-dimensional conformal field theory, we analyze conformally invariant boundary conditions which break part of the bulk symmetries. When the subalgebra that is preserved by the boundary

Lattice realizations of the open descendants of twisted boundary conditions for sl(2) A–D–E models
The twisted boundary conditions and associated partition functions of the conformal sl(2) A–D–E models are studied on the Klein bottle and the Mobius strip. The A–D–E minimal lattice models give
TFT construction of RCFT correlators I: Partition functions
Branes: From free fields to general backgrounds
Abstract Motivated by recent developments in string theory, we study the structure of boundary conditions in arbitrary conformal field theories. A boundary condition is specified by two types of


The A-D-E classification of minimal andA1(1) conformal invariant theories
We present a detailed and complete proof of our earlier conjecture on the classification of minimal conformal invariant theories. This is based on an exhaustive construction of all modular invariant

We show that D-branes, extended objects defined by mixed Dirichlet-Neumann boundary conditions, break half the supersymmetries of the type II superstring and carry a complete set of electric and
Non-abelian bosonization in two dimensions
A non-abelian generalization of the usual formulas for bosonization of fermions in 1+1 dimensions is presented. Any fermi theory in 1+1 dimensions is equivalent to a local bose theory which
