Nappi-Witten vertex operator algebra via inverse Quantum Hamiltonian Reduction
Drazen Adamovic, Andrei Babichenko
The representation theory of the Nappi-Witten VOA was initiated in arXiv:1104.3921 and arXiv:2011.14453. In this paper we use the technique of inverse quantum hamiltonian reduction…

Representations of the Nappi--Witten vertex operator algebra
Andrei Babichenko, Kazuya Kawasetsu, David Ridout +1
The Nappi-Witten model is a Wess-Zumino-Witten model in which the target space is the nonreductive Heisenberg group . We consider the representation theory underlying this con…
