»Holomorphic curves and Seiberg-Witten invariants for 4-dimensional cobordisms«

Abstract:
We will discuss a variant of SW → Gr theorem in the context of a 4-manifold with cylindrical ends, equipped with a nontrivial harmonic 2-form. This harmonic 2-form is allowed to be asymptotic to 0 on some (but not all) of its ends, and may have nondegenerate zeros along 1-submanifolds. Positivity results associated to some simple special cases constitute a key ingredient in the proof of HM = HF. The aforementioned general theorem is motivated by (potential) generalizations of the HM = HF and the HM = PFH theorems.

 

Hierzu ergeht herzliche Einladung.
