Twisted logarithmic modules of lattice vertex algebras
Bojko Bakalov, McKay Sullivan
Twisted modules over vertex algebras formalize the relations among twisted vertex operators and have applications to conformal field theory and representation theory. A recent gene…

Inhomogeneous supersymmetric bilinear forms
Bojko Bakalov, McKay Sullivan
We consider inhomogeneous supersymmetric bilinear forms, i.e., forms that are neither even nor odd. We classify such forms up to dimension seven in the case when the restrictions o…

Twisted logarithmic modules of free field algebras
Bojko Bakalov, McKay Sullivan
Given a non-semisimple automorphism of a vertex algebra , the fields in a -twisted -module involve the logarithm of the formal variable, and the action of the Virasoro…
