On mode transition algebras for -graded vertex algebras and applications to bosonic ghosts
Katrina Barron, Justine Fasquel, Florencia Orosz Hunziker +1
We study the mode transition algebras and Zhu algebras in the setting of -graded vertex algebras, with particular focus on the Weyl vertex algebra at central charge 2 (…

Graded pseudo-traces for strongly interlocked modules for a vertex operator algebra and applications
Katrina Barron, Karina Batistelli, Florencia Orosz Hunziker +1
We define the notion of {\it strongly interlocked} for indecomposable generalized modules for a vertex operator algebra, and show that the notion of graded pseudo-trace is well def…
