Hyperbolic Manifolds, Harmonic Forms, and Seiberg-Witten Invariants
New estimates are derived concerning the behavior of self-dual hamonic 2-forms on a compact Riemannian 4-manifold with non-trivial Seiberg-Witten invariants. Applications include a vanishing theorem for certain Seiberg-Witten invariants on compact 4-manifolds of constant negative sectional curvature.
متن کاملIntersection theory of coassociative submanifolds in G2-manifolds and Seiberg-Witten invariants
We study the problem of counting instantons with coassociative boundary condition in (almost) G2-manifolds. This is analog to the open GromovWitten theory for counting holomorphic curves with Lagrangian boundary condition in Calabi-Yau manifolds. We explain its relationship with the Seiberg-Witten invariants for coassociative submanifolds. Intersection theory of Lagrangian submanifolds is an es...
متن کاملHiggs Bundles and Four Manifolds
It is known that the Seiberg-Witten invariants, derived from supersymmetric Yang-Mill theories in four-dimensions, do not distinguish smooth structure of certain non-simply-connected four manifolds. We propose generalizations of Donaldson-Witten and Vafa-Witten theories on a Kähler manifold based on Higgs Bundles. We showed, in particular, that the partition function of our generalized Vafa-Wit...
متن کاملSeiberg-Witten invariants of mapping tori, symplectic fixed points, and Lefschetz numbers
Let f : Σ → Σ be an orientation preserving diffeomorphism of a compact oriented Riemann surface. This paper relates the Seiberg-Witten invariants of the mapping torus Yf to the Lefschetz invariants of f .
متن کاملRefined Seiberg-witten Invariants
In the past two decades, gauge theoretic methods became indispensable when considering manifolds in dimension four. Initially, research centred around the moduli spaces of Yang-Mills instantons. Simon Donaldson had introduced the instanton equations into the field. Using cohomological data of the corresponding moduli spaces, he defined invariants which could effectively distinguish differentiab...
