Modular functors from conformal blocks of rational vertex operator algebras
Chiara Damiolini, Lukas Woike
For a vertex operator algebra , one may naturally define spaces of conformal blocks following a construction of Frenkel-Ben-Zvi generalized by Damiolini-Gibney-Tarasca. If i…

Conformal blocks on smoothings via mode transition algebras
Chiara Damiolini, Angela Gibney, Daniel Krashen
Here we define a series of associative algebras attached to a vertex operator algebra , called mode transition algebras, showing they reflect both algebraic properties of an…
