Rank one lattice type vertex operator algebras and their automorphism groups, II: E-series

Chongying Dong, Robert L. Griess, Alex Ryba

Let L be the A_1 root lattice and G a finite subgroup of Aut(V_L), where $V_L$ is the associated lattice VOA (in this case, Aut(V) is isomorphic to PSL(2,\Bbb C)). The fixed point…
