The coupling of the closed string to the open string in the topological B-model was studied in this article, where it was shown that this coupling induces an isomorphism of Gerstenhaber algebras on the level of cohomology.
Abstract
We study the coupling of the closed string to the open string in the topological B-model. These couplings can be viewed as gauge invariant observables in the open string field theory, or as deformations of the differential graded algebra describing the OSFT. This is interpreted as an intertwining map from the closed string sector to the deformation (Hochschild) complex of the open string algebra. By an explicit calculation we show that this map induces an isomorphism of Gerstenhaber algebras on the level of cohomology. Reversely, this can be used to derive the closed string from the open string. We shortly comment on generalizations to other models, such as the A-model.

Landau-Ginzburg Realization of Open String TFT

TL;DR: In this article, the authors investigated B-type topological Landau-Ginzburg theory with one variable, with D2brane boundary conditions, and determined the allowed brane configurations in terms of the possible factorizations of the superpotential, and computed the corresponding open string chiral rings.

Lectures on AKSZ Sigma Models for Physicists

TL;DR: The AKSZ construction as mentioned in this paper is a mathematical formulation for the construction and analyses of a large class of TFTs; it was inspired by the Batalin-Vilkovisky formalism of gauge theories.

String theory and noncommutative geometry

TL;DR: In this article, a non-zero B-field is introduced for string theory and the entire string dynamics is described by a minimally coupled (supersymmetric) gauge theory on a noncommutative space, and the corrections away from this limit are discussed.

Noncommutative Geometry and Matrix Theory: Compactification on Tori

TL;DR: In this paper, the authors studied toroidal compactification of Matrix theory, using ideas and results of non-commutative geometry, and argued that they correspond in supergravity to tori with constant background three-form tensor field.

Non-commutative geometry and string field theory

TL;DR: In this paper, an attempt is made to interpret the interactions of bosonic open strings as defining a non-cummulative, associative algebra, and to formulate the classical non-linear field theory of such strings in the language of non-commulative geometry.

Kodaira-Spencer theory of gravity and exact results for quantum string amplitudes

TL;DR: In this paper, the authors developed techniques to compute higher loop string amplitudes for twisted N = 2 theories with ε = 3 (i.e. the critical case) by exploiting the discovery of an anomaly at every genus in decoupling of BRST trivial states, captured by a master anomaly equation.
