Conformal field theories associated to regular chiral vertex operator algebras I: theories over the projective line
Kiyokazu Nagatomo, Akihiro Tsuchiya
Based on any chiral vertex operator algebra satisfying a suitable finiteness condition, the semisimplicity of the zero-mode algebra as well as a regularity for induced modules, we…
