Conformal blocks for modular vertex algebras
Colton Griffin
Given a vertex operator algebra over , it is known how to define so-called sheaves of coinvariants and conformal blocks on the moduli space $\overline{\mathcal{M}}_…

Modular Zhu algebra theory and Virasoro vertex algebras
Colton Griffin
We develop the representation theory of vertex algebras over arbitrary commutative rings as part of a relative theory, suitable for various applications such as the study of modula…
