Vertex operator algebras (VOAs) lie at the intersection of mathematics and theoretical physics, providing a rigorous algebraic framework for two-dimensional conformal field theories (CFTs). These ...
It is proved that the vertex operator algebra V is isomorphic to the moonshine VOA V of Frenkel-Lepowsky-Meurman if it satisfies conditions (a,b,c,d) or (a',b,c,d). These conditions are: (a) V is the ...
