Conformal Boundary Conditions and what they teach us
V. B. Petkova, J. -B. Zuber
The question of boundary conditions in conformal field theories is discussed, in the light of recent progress. Two kinds of boundary conditions are examined, along open boundaries…
The many faces of Ocneanu cells
V. B. Petkova, J. -B. Zuber
We define generalised chiral vertex operators covariant under the Ocneanu ``double triangle algebra'' {\cal A}, a novel quantum symmetry intrinsic to a given rational 2-d conformal…
On the Classification of Bulk and Boundary Conformal Field Theories
R. Behrend, P. Pearce, V. Petkova +1
The classification of rational conformal field theories is reconsidered from the standpoint of boundary conditions. Solving Cardy's equation expressing the consistency condition on…
From CFT's to Graphs
V. B. Petkova, J. -B. Zuber
In this paper, we pursue the discussion of the connections between rational conformal field theories (CFT) and graphs. We generalize our recent work on the relations of operator pr…
On Structure Constants of Theories
V. B. Petkova, J. -B. Zuber
Structure constants of minimal conformal theories are reconsidered. It is shown that {\it ratios} of structure constants of spin zero fields of a non-diagonal theory over the same…
