Abstract.The paper contains a proof that elliptic genus of a Calabi-Yau manifold is a Jacobi form, finds in which dimensions the elliptic genus is determined by the Hodge numbers and shows that elliptic genera of a Calabi-Yau hypersurface in a toric variety and its mirror coincide up to sign. The proof of the mirror property is based on the extension of elliptic genus to Calabi-Yau hypersurfaces in toric varieties with Gorenstein singularities. 
On Equivariant Elliptic Genera of Toric Calabi-Yau 3-folds
We show that equivariant elliptic genera of toric Calabi-Yau 3-folds are generalized weak Jacobi forms. We also introduce a notion of averaged equivariant elliptic genera of toric Calabi-Yau 3-folds,
Elliptic genera of singular varieties
The notions of orbifold elliptic genus and elliptic genus of singular varieties are introduced, and the relation between them is studied. The elliptic genus of singular varieties is given in terms of
Orbifold elliptic genus and elliptic genus of singular varieties are introduced and relation between them is studied. Elliptic genus of singular varieties is given in terms of a resolution of
Multi-fan is an analogous notion of fan in toric theory. Fan is a combinatorial object associated to a toric variety. Multi-fan is associated to an orbifold with an action of half the dimension of
Elliptic genus of singular algebraic varieties and quotients
This paper discusses the basic properties of various versions of the twovariable elliptic genus with special attention to the equivariant elliptic genus. The main applications are to the elliptic
Elliptic genera, real algebraic varieties and quasi-Jacobi forms
The first part surveys the push forward formula for elliptic class and various applications obtained in the papers by L.Borisov and the author. In the remaining part we discuss the ring of
Deformations of Vertex Algebras, Quantum Cohomology of Toric Varieties, and Elliptic Genus
Abstract: We use previous work on the chiral de Rham complex and Borisov's deformation of a lattice vertex algebra to give a simple linear algebra construction of quantum cohomology of toric
Elliptic genera of singular varieties, orbifold elliptic genus and chiral de Rham complex.
This paper surveys the authors’ recent work on the two-variable elliptic genus of singular varieties. The last section calculates a generating function for the elliptic genera of symmetric products.
Mirror symmetry formulae for the elliptic genus of complete intersections
In this paper, we calculate the elliptic genus of certain complete intersections in products of projective spaces. We show that it is equal to the elliptic genus of the Landau–Ginzburg models that
We show that elliptic classes introduced in [7] for spaces with infinite fundamental groups yield Novikov’s type higher elliptic genera which are invariants of Kequivalence. This include, as a


Elliptic Genera of Symmetric Products and Second Quantized Strings
Abstract: In this note we prove an identity that equates the elliptic genus partition function of a supersymmetric sigma model on the N-fold symmetric product of a manifold M to the partition
Complex vector bundles and Jacobi forms
The elliptic genus (EG) of a compact complex manifold was introduced as a holomorphic Euler characteristic of some formal power series with vector bundle coefficients. EG is an automorphic form in

Vertex Algebras and Mirror Symmetry
Abstract: Mirror Symmetry for Calabi–Yau hypersurfaces in toric varieties is by now well established. However, previous approaches to it did not uncover the underlying reason for mirror varieties to
