Seiberg-Witten Equations on Three-Manifolds with Euclidean Ends

Yi-Jen Lee

We construct the Seiberg-Witten theory on 3-manifolds with Euclidean ends (connected sums of $R^{3}$ and a compact manifold) with perturbations which approximate $* d x_{3}$ at infinity…

Circle-valued Morse theory and Reidemeister torsion

Michael Hutchings, Yi-Jen Lee

Let X be a closed manifold with zero Euler characteristic, and let f: X --> S^1 be a circle-valued Morse function. We define an invariant I which counts closed orbits of the gradie…

Circle-valued Morse theory, Reidemeister torsion, and Seiberg-Witten invariants of 3-manifolds

Michael Hutchings, Yi-Jen Lee

Let X be a compact oriented Riemannian manifold and let $ϕ : X \to S^{1}$ be a circle-valued Morse function. Under some mild assumptions on $ϕ$ , we prove a formula relating: (a) the num…
