The theory of C2-cofinite VOAs Gannon, Terry
Rational VOAs are by now quite well understood: their representation theory is captured by a modular tensor category; their characters define a vector-valued modular form for $SL(2,Z)$; etc. The class of C2-cofinite (logarithmic) VOAs is the natural generalisation of rationality, but their theory is still much less clear. This talk reviews and contributes to this theory. It is joint work with Thomas Creutzig.
