An operadic approach to vertex algebra and Poisson vertex algebra cohomology

Introduction to the vertex algebra approach to mirror symmetry

The goal of this paper is to make the vertex operator algebra approach to mirror symmetry accessible to algebraic geometers. Compared to betterknown approaches using moduli spaces of stable maps and special Lagrangian fibrations, this approach follows more closely the original line of thinking that lead to the discovery of mirror symmetry by physicists. The ultimate goal of the vertex algebra a...

Comma Vertex and String Field Algebra

We study the matter part of the algebra of open string fields using the 3-string vertex over the sliver state, which we call “comma vertex”. By generalizing this comma vertex to the N -string overlap, we obtain a closed form of the Neumann coefficients in the N -string vertex and discuss its relation to the oscillator representation of wedge states.

A Characetrization of Vertex Operator Algebra L(

It is shown that any simple, rational and C2-cofinite vertex operator algebra whose weight 1 subspace is zero, the dimension of weight 2 subspace is greater than or equal to 2 and with central charge c = 1, is isomorphic to L(12 , 0) ⊗ L( 1 2 , 0). 2000MSC:17B69
