On Operad Structures of Moduli Spaces and String Theory

We construct a real compactification of the moduli space of punctured rational algebraic curves and show how its geometry yields operads governing homotopy Lie algebras, gravity algebras and Batalin-Vilkovisky algebras. These algebras appeared recently in the context of string theory, and we give a simple deduction of these algebraic structures from the formal axioms of conformal field theory a...

On the Moduli Spaces of M(atrix)-Theory Compactifications

By identifying the moduli space of coupling constants in the SYM description of toroidal compactifications of M(atrix)-Theory, we construct the M(atrix) description of the moduli spaces of Type IIA string theory compactified on T . Addition of theta terms to the M(atrix) SYM produces the shift symmetries necessary to recover the correct global structure of the moduli spaces. Up to n = 3, the co...

Moduli Spaces and Invariant Theory

A moduli space is a space that parametrizes geometric objects. For example, elliptic curves are classified by the so-called J-invariant, so the moduli space of elliptic curves is a line (with coordinate J). More generally, there exists a moduli space, calledMg , which parametries all projective algebraic curves of genus g (equivalently, all compact Riemann surfaces of genus g). The Jacobian of ...

Vertex Operators and the Geometry of Moduli Spaces of Framed Torsion-free Sheaves

We define complexes of vector bundles on products of moduli spaces of framed rank r torsion-free sheaves on P. The top non-vanishing equivariant Chern classes of the cohomology of these complexes yield actions of the r-colored Heisenberg and Clifford algebras on the equivariant cohomology of the moduli spaces. In this waywe obtain a geometric realization of the boson-fermion correspondence and ...

Moduli spaces of surfaces and real structures

We give infinite series of groups Γ and of compact complex surfaces of general type S with fundamental group Γ such that 1) any surface S′ with the same Euler number as S, and fundamental group Γ, is diffeomorphic to S 2) the moduli space of S consists of exactly two connected components, exchanged by complex conjugation. Whence, i) on the one hand we give simple counter-examples to the DEF = D...
