ON THE BACKGROUND INDEPENDENCE OF STRING FIELD THEORY III. Explicit Field Redefinitions
Given two conformal field theories related to each other by a marginal perturbation, and string field theories constructed around such backgrounds, we show how to construct explicit redefinition of string fields which relate these two string field theories. The analysis is carried out completely for quadratic and cubic terms in the action. Although a general proof of existence of field redefini...

متن کاملOn background-independent open-string field theory.
A framework for background independent open-string field theory is proposed. The approach involves using the BV formalism – in a way suggested by recent developments in closed-string field theory – to implicitly define a gauge invariant Lagrangian in a hypothetical “space of all open-string world-sheet theories.” It is built into the formalism that classical solutions of the string field theory...
متن کاملField Redefinitions in String Theory as a Solution Generating Technique
The purpose of this work is to show that there exists an additional invariance of the βfunction equations of string theory on d + 1-dimensional targets with d toroidal isometries. It corresponds to a shift of the dilaton field and a scaling of the lapse function, and is reminiscent of string field redefinitions. While it preserves the form of the β-function equations, it changes the effective a...
متن کاملOpen-Closed String Field Theory in the Background B-Field
In this paper, we study open-closed string field theory in the background B-field in the so-called α = p formulation. The string field theory in the infrared gives noncommutative gauge theory in the open string sector. Since this theory includes closed string fields as dynamical variables, we can obtain another string field theory in the same background through the condensation of closed string...
