Comma Vertex and String Field Algebra

چکیده
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.

Siegel Gauge in Vacuum String Field Theory
We study the star algebra of ghost sector in vacuum string field theory (VSFT). We show that the star product of two states in the Siegel gauge is BRST exact if we take the BRST charge to be the one found in [1], and the BRST exact states are nil factors in the star algebra. By introducing a new star product defined on the states in the Siegel gauge, the equation of motion of VSFT is characteri...

We introduce notions of open-string vertex algebra, conformal open-string vertex algebra and variants of these notions. These are " open-string-theoretic, " " noncommutative " generalizations of the notions of vertex algebra and of conformal vertex algebra. Given an open-string vertex algebra, we show that there exists a vertex algebra, which we call the " meromorphic center, " inside the origi...
متن کاملN-string vertices in string field theory.
We give the general form of the vertex corresponding to the interaction of an arbitrary number of strings. The technique employed relies on the “comma” representation of String Field Theory where string fields and interactions are represented as matrices and operations between them such as multiplication and trace. The general formulation presented here shows that the interaction vertex of N st...

In is shown explicitly that the Witten's interaction 3-vertex is a solution to the comma overlap equations; hence establishing the equivalence between the conventional and the " comma " formulation of interacting string theory at the level of vertices.
متن کاملMeromorphic open-string vertex algebras
A notion of meromorphic open-string vertex algebra is introduced. A meromorphic open-string vertex algebra is an open-string vertex algebra in the sense of Kong and the author satisfying additional rationality (or meromorphicity) conditions for vertex operators. The vertex operator map for a meromorphic open-string vertex algebra satisfies rationality and associativity but in general does not s...
