We consider the interplay of infinite-dimensional Lie algebras of Virasoro type and moduli spaces of curves, suggested by string theory. We will see that the infinitesimal geometry of determinant bundles is governed by Virasoro symmetries. The Mumford forms are just invariants of these symmetries. The representations of Virasoro algebra define (twisted)D-modules on moduli spaces; theseD-modules are equations on correlators in conformal field theory. 
Vertex algebras of CohFT-type
Representations of certain vertex algebras, here called of CohFT-type, can be used to construct vector bundles of coinvariants and conformal blocks on moduli spaces of stable curves [DGT2]. We show
Realizations of conformal current-type Lie algebras
In this paper we obtain the realizations of some infinite-dimensional Lie algebras, named “conformal current-type Lie algebras,” in terms of a two-dimensional Novikov algebra and its deformations.
Conformal blocks from vertex algebras and their connections on ℳg,n
We show that coinvariants of modules over conformal vertex algebras give rise to quasi-coherent sheaves on moduli of stable pointed curves. These generalize Verlinde bundles or vector bundles of

In this paper, we treat moduli spaces of parabolic connections. We take \'etale coverings of the moduli spaces, and we construct a Hamiltonian structure of an algebraic vector field determined by the
Symmetries, sato theory, and tau functions
We relate Virasoro (conformal) symmetries with a subset of generators of the algebra and show their connection to the symmetries of [8] arising from Virasoro action on gauge operat tors . We a1so
We apply the technique of localization for vertex algebras to the Segal- Sugawara construction of an "internal" action of the Virasoro algebra on affine Kac- Moody algebras. The result is a lifting
Superconformal Vertex Algebras and Jacobi Forms
We discuss the appearance of Jacobi automorphic forms in the theory of superconformal vertex algebras, explaining it by way of supercurves and formal geometry. We touch on some related topics such as
Ginzburg algebras and the Hitchin connection for parabolic G-bundles
For a simple, simply connected, complex group G, we prove the existence of a flat projective connection on the bundle of nonabelian theta functions on the moduli space of semistable parabolic


Analytic torsion and holomorphic determinant bundles I. Bott-Chern forms and analytic torsion
We attach secondary invariants to any acyclic complex of holomorphic Hermitian vector bundles on a complex manifold. These were first introduced by Bott and Chern [Bot C]. Our new definition uses
Quantum field theory, Grassmannians, and algebraic curves
This paper is devoted in part to clarifying some aspects of the relation between quantum field theory and infinite Grassmannians, and in part to pointing out the existence of a close analogy between
Duality and intersection theory in complex manifolds. I
We introduce the concept of a twisting cochain and a twisted complex associated to a coherent sheaf. For sheaves of submanifolds these twisted complexes are used to construct on cochain level the
Geometric realization of conformal field theory on Riemann surfaces
Conformal field theory on a family of Riemann surfaces is formulated. We derive equations of motion of vacua which are parametrized by moduli of Riemann surfaces and show that these vacua are
Analytic fields on Riemann surfaces. II
AbstractThe properties of analytic fields on a Riemann surface represented by a branch covering of ℂℙ1 are investigated in detail. Branch points are shown to correspond to the vertex operators with
