“…This technical lemma was originally proved for closed symplectic 4-manifolds in [41, Lemma 3.1] (see also [77,Theorem 5.1]), and we will prove it at the end of Section 1.3. By intersection positivity of J-holomorphic curves, a J-holomorphic exceptional sphere is the unique J-holomorphic curve in its homology class.…”

“…Proof of Lemma 1.3.12. We follow the proof of [77,Theorem 5.1]. Given a symplectic exceptional sphere in the class e ∈ E ω , we can always construct a (probably non-generic) cobordism-admissible almost complex structure J 0 on (X, ω) which is integrable in a neighborhood of the sphere.…”

“…In this section we study the homology of this subcomplex. We show that for a properly chosen pair .f; J /, the homology of .C U ı .f /; @j U ı / coincides with the homology of U, namely, (24) H .C U ı .f /; @j U ı / Š H .U /:…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
