Vertex Operator Algebra

Vertex Operator Algebra. This operator is written as : There is some evidence that all rational conformal field theories can be obtained from the wzw models by means of two standard constructions, namely by considering cosets and taking orbifolds;

To use this theory, one first has to verify that the vertex operator algebra satisfies certain conditions. We show in the present paper that for any vertex operator algebra containing a vertex operator subalgebra isomorphic to a tensor. Thus rational conformal field theory seems to have something of the.

Generalized vertex operator for every element of v instead of just for elements of r. There exists a vertex operator algebra (voa) v \of central charge 24 called the moonshine module which has the monster, the largest sporadic group, as its automorphism group.

The elements of a vertex operator algebra correspond to (abstract) vertex operators , which in special cases include many of the vertex operators introduced by physicists in the early days of string theory to describe hypothesized interactions of certain elementary particles at a vertex (cf. A vertex algebra consists of the following data:

De nition a voa v of central charge c is a tuple (v;1;!;y) consisting of a graded complex vector space v = l 1 n=0 v n with two elements 1 2v 0 and !2v 2 and a linear map y : First we associate the lie algebra of physical states to a vertex operator algebra of central charge c=24.

Vertex operator algebras (voas) are mathematical objects describing 2d chiral conformal field theory. The representation category of a “strongly rational” voa is a modular tensor category (which yields a 3d topological quantum field theory), and conjecturally, all modular tensor categories arise from such voa representations.

Let v be a vertex operator algebra satisfying the following conditions: We can generalize for n2z, a(w) nb(w) := res z(a(z)b(w)(z w)n b(w)a(z)( w+ z)n) (2.6) For an integral form in a vertex operator algebra (voa), we require closure under the given countably many products, plus a few additional conditions.

Griess, robert (university of michigan) integral forms in vertex operator algebras an integral form in an algebra is the integral span of a basis which is closed under the product. The representation category of a “strongly rational” voa is a modular tensor category (which yields a 3d topological quantum field theory), and conjecturally, all modular tensor categories arise from such voa representations.

The Theory Of Vertex (Operator) Algebras Has Developed Rapidly In The Last Few Years.

For the proof, see [fbz] proposition 3.3.1. We study the corresponding lie bracket as a bilinear map between weight spaces of the vertex operator algebra. The relevant vertex operator algebra is then generated by the loop group symmetries.
