Some refined higher type adjunction inequalities on 4-manifolds

preprint2014arXivOpen access

Abstract

We further sharpen higher type adjunction inequalities of P. Ozsváth and Z. Szabó on a 4-manifold MM with a nonzero Seiberg-Witten invariant for a Spinc^c structure s\frak{s}, when an embedded surface Σ⊂MΣ\subset M satisfies [Σ]⋅[Σ]≥0[Σ]\cdot [Σ]\geq 0 and ∣⟨[Σ],c1(s)⟩∣+[Σ]⋅[Σ]≥2b1(M).|\langle [Σ],c_1(\frak{s})\rangle|+[Σ]\cdot [Σ]\geq 2b_1(M).
