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,
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
Homotopy Batalin–Vilkovisky algebras
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


Homotopy Gerstenhaber algebras and topological field theory
We prove that the BRST complex of a topological conformal field theory is a homotopy Gerstenhaber algebra, as conjectured by Lian and Zuckerman in 1992. We also suggest a refinement of the original
The homotopy Gerstenhaber algebra of Hochschild cochains of a regular algebra is formal
The solution of Deligne's conjecture on Hochschild cochains and the formality of the operad of little disks provide us with a natural homotopy Gerstenhaber algebra structure on the Hochschild
Homotopy Gerstenhaber algebras
The purpose of this paper is to complete Getzler-Jones’ proof of Deligne’s Conjecture, thereby establishing an explicit relationship between the geometry of configurations of points in the plane and
Courant Algebroids and Strongly Homotopy Lie Algebras
Courant algebroids are structures which include as examples the doubles of Lie bialgebras and the direct sum of tangent and cotangent bundles with the bracket introduced by T. Courant for the study
The sh Lie Structure of Poisson Brackets in Field Theory
Abstract:A general construction of an sh Lie algebra (L∞-algebra) from a homological resolution of a Lie algebra is given. It is applied to the space of local functionals equipped with a Poisson
Deformations of algebras over operads and Deligne's conjecture
In present paper we develop the deformation theory of operads and algebras over operads. Free resolutions (constructed via Boardman-Vogt approach) are used in order to describe formal moduli spaces
Generalized Calabi-Yau manifolds
A geometrical structure on even-dimensional manifolds is defined which generalizes the notion of a Calabi-Yau manifold and also a symplectic manifold. Such structures are of either odd or even type
Courant Algebroids and Strongly and Strongly Homotopy Lie Algebras
Courant algebroids are structures which include as examples the doubles of Lie bialgebras and the bundle TM⊕ T*M with the bracket introduced by T. Courant for the study of Dirac structures. Within

A classical E-infinity operad is formed by the bar construction of the symmetric groups. Such an operad has been introduced by M. Barratt and P. Eccles in the context of simplicial sets in order to
New perspectives on the BRST-algebraic structure of string theory
Motivated by the descent equation in string theory, we give a new interpretation for the action of the symmetry charges on the BRST cohomology in terms of what we callthe Gerstenhaber bracket. This
