$B M S_{3}$ -like algebras via the $Z_{N}$ -graded $u (1)^{2}$ Kac-Moody algebra

Armin Ghazi, Ahmad Moradpouri

The Sugawara construction provides a natural way to construct the Virasoro algebra from a current algebra. It was shown in Ref.~\cite{Ghazi:2025oin} that for the $u (1)^{2}$ Kac-Moody…

The $Z_{N}$ equivariant Virasoro algebra via alternative Sugawara constructions

Armin Ghazi, Ahmad Moradpouri

In this paper, we study the $u (1)^{2}$ Kac--Moody algebra and generalize the standard Sugawara construction of the Virasoro algebra to an infinite family of new realizations. In this…
