TL;DR: In this paper, a general method to construct bulk-deformed open topological string theories from Landau-Ginzburg models is presented, based on a coherent treatment of the problem in terms of the fundamental A-infinity-and L-ininity-structures involved.
Abstract: We present a general method to construct bulk-deformed open topological string theories from Landau-Ginzburg models. To this end we obtain a weak version of deformation quantisation, and we show how this together with the technique of homological perturbation allows to explicitly compute all bulk-deformed open topological string amplitudes at tree-level before tadpole-cancellation. Our approach is based on a coherent treatment of the problem in terms of the fundamental A-infinity- and L-infinity-structures involved.

TL;DR: In this paper, it was shown that W 1+∞ constraints, a subset of the correlation functions and the integrable hierarchy of the two-matrix model, correspond exactly to the W 1 + ∞ constraints.

TL;DR: In this paper, a 2,0 supersymmetric action in six dimensions was constructed, which describes a tensor multiplet interacting with a self-dual string, and the action is invariant under a local symmetry.
Abstract: We construct a unique (2,0) supersymmetric action in six dimensions, describing a tensor multiplet interacting with a self-dual string. It is a sum of four terms: A free kinetic term for the tensor multiplet fields integrated over Minkowski space, a Nambu-Goto type kinetic term for the string integrated over the string world-sheet, a Wess-Zumino type electromagnetic coupling integrated over the world-volume of a Dirac membrane attached to the string, and a direct interaction of such Dirac membranes. In addition to supersymmetry, the action is also invariant under a local symmetry, which allows us to choose the Dirac membrane world-volume freely and eliminate half of the fermionic degrees of freedom on the string world-sheet.

TL;DR: In this paper, local Lorentz and gauge anomalies in the sigma model describing the propagation of the heterotic string in an arbitrary background field are discussed in the superspace formulation.

TL;DR: In this paper, a topological theory which contains explicitly Kodaira-Spencer deformation theory was proposed, and it was shown that three-point correlation functions give the Yakawa couplings for a generic point in the moduli space of complex structures.
