Seiberg–Witten Invariants and Pseudo-Holomorphic Subvarieties for Self-Dual, Harmonic 2–Forms
A smooth, compact 4–manifold with a Riemannian metric and b2+ ≥ 1 has a non-trivial, closed, self-dual 2–form. If the metric is generic, then the zero set of this form is a disjoint union of circles. On the complement of this zero set, the symplectic form and the metric define an almost complex structure; and the latter can be used to define pseudo-holomorphic submanifolds and subvarieties. The...
متن کاملLocal Properties of Self-Dual Harmonic 2-forms on a 4-Manifold
We will prove a Moser-type theorem for self-dual harmonic 2-forms on closed 4manifolds, and use it to classify local forms on neighborhoods of singular circles on which the 2-form vanishes. Removing neighborhoods of the circles, we obtain a symplectic manifold with contact boundary we show that the contact form on each S1×S2, after a slight modification, must be one of two possibilities.
متن کاملNowhere-zero flow polynomials
In this article we introduce the flow polynomial of a digraph and use it to study nowherezero flows from a commutative algebraic perspective. Using Hilbert’s Nullstellensatz, we establish a relation between nowhere-zero flows and dual flows. For planar graphs this gives a relation between nowhere-zero flows and flows of their planar duals. It also yields an appealing proof that every bridgeless...
متن کاملAlmost harmonic spinors
We show that any closed spin manifold not diffeomorphic to the two-sphere admits a sequence of volume-one-Riemannian metrics for which the smallest non-zero Dirac eigenvalue tends to zero. As an application, we compare the Dirac spectrum with the conformal volume. Spineurs presque harmoniques Résumé. Nous montrons que, sur toute variété spinorielle compacte sans bord non difféomorphe à la sphèr...
متن کاملNowhere-zero 5-flows
We prove that every cyclically 6-edge-connected cubic graph with oddness at most 4 has a nowhere-zero 5-flow. Therefore, a possible minimum counterexample to the 5-flow conjecture has oddness at least 6.
