We provide a simple construction of a G ∞ -algebra structure on an important class of vertex algebras V, which lifts the Gerstenhaber algebra structure on BRST cohomology of V introduced by Lian and Zuckerman. We outline two applications to algebraic topology: the construction of a sheaf of G ∞  algebras on a Calabi–Yau manifold M, extending the operations of multiplication and bracket of functions and vector fields on M, and of a Lie ∞  structure related to the bracket of Courant (Trans Amer…

Quasiclassical Lian-Zuckerman Homotopy Algebras, Courant Algebroids and Gauge Theory
We define a quasiclassical limit of the Lian-Zuckerman homotopy BV algebra (quasiclassical LZ algebra) on the subcomplex, corresponding to “light modes”, i.e. the elements of zero conformal weight,
HOMOTOPY RELATIONS FOR TOPOLOGICAL VOA
We consider a parameter-dependent version of the homotopy associative part of the Lian–Zuckerman homotopy algebra and provide an interpretation of the multilinear operations of this algebra in terms
Beltrami–Courant differentials and $G_{\infty}$-algebras
Using the symmetry properties of two-dmensional sigma models, we introduce a notion of the Beltrami-Courant differential, so that there is a natural homotopy Gerstenhaber algebra related to it. We
β-γ systems and the deformations of the BRST operator
We describe the relation between simple logarithmic CFTs associated with closed and open strings, and their 'infinite metric' limits, corresponding to the β–γ systems. This relation is studied on the

This paper provides an explicit cobrant resolution of the operad encoding Batalin{Vilkovisky algebras. Thus it denes the notion of homotopy Batalin{Vilkovisky algebras with the required homotopy
Generalized Calabi-Yau manifolds and the chiral de Rham complex

Abstract We show that the chiral de Rham complex of a generalized Calabi–Yau manifold carries N = 2 supersymmetry. We discuss the corresponding topological twist for this N = 2 algebra. We interpret
Sigma-models and Homotopy Algebras
We review the relation between homotopy algebras of conformal field theory and geometric structures arising in sigma models. In particular we formulate conformal invariance conditions, which in the
Cotorsion Pairs in a Recollement of Triangulated Categories
In the present article, we study the relationship of cotorsion pairs among three triangulated categories in a recollement. We show that if a triangulated category 𝒟 admits a recollement relative to
On higher order Leibniz identities in TCFT
We extend the algebra of local observables in topological conformal field theories by nonlocal operators. This allows to construct parameter-dependent operations realized via certain integrals over
