Galilean $W_3$ algebra

Abstract

Galilean $W_3$ vertex operator algebra $\mathcal{G}{W}_3(c_L,c_M)$ is constructed as a universal enveloping vertex algebra of certain non-linear Lie conformal algebra. It is proved that this algebra is simple by using determinant formula of the vacuum module. Reducibility criterion for Verma modules is given, and the existence of subsingular vectors demonstrated. Free field realisation of $\mathcal{G}{W}_3(c_L,c_M)$ and its highest weight modules is obtained within a rank 4 lattice VOA.
