The Automorphism Group of the Vertex Operator Algebra Vₗ+ for an even lattice L without roots
Shimakura, Hiroki
Original · EN
The automorphism group of the vertex operator algebra Vₗ+ is studied by using its action on isomorphism classes of irreducible Vₗ+-modules. In particular, the shape of the automorphism group of Vₗ+ is determined when L is isomorphic to an even unimodular lattice without roots, √2R for an irreducible root lattice R of type ADE and the Barnes-Wall lattice of rank 16.
