Genus-zero Permutation-twisted Conformal Blocks for Tensor Product Vertex Operator Algebras: The Tensor-factorizable Case
Bin Gui
For a vertex operator algebra , we construct an explicit isomorphism between the space of genus-0 conformal blocks associated to permutation-twisted -modules and…

Sewing and Propagation of Conformal Blocks
Bin Gui
We clarify the relations between sewing and propagating conformal blocks. In particular, we show that sewing and propagation and commuting procedures. As an application, we give a…
