Logarithmic bulk and boundary conformal field theory and the full centre construction

Understand

We review the definition of bulk and boundary conformal field theory in a way suited for logarithmic conformal field theory.

• The notion of a maximal bulk theory which can be non-degenerately joined to a boundary theory is defined.
• The purpose of this construction is to obtain the more complicated bulk theories from simpler boundary theories.
• We then describe the algebraic counterpart of the maximal bulk theory, namely the so-called full centre of an algebra in an abelian braided monoidal category.
