Δ Invariants of Plumbed Manifolds
We study the minimal -exponent Δ in the BPS -series Ẑ of negative definite plumbed 3-manifolds equipped with a spinc-structure. We express the Δ of Seifert manifolds in terms of an invariant commonly used in singularity theory. We provide several examples illustrating the interesting behaviour of Δ...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | We study the minimal -exponent Δ in the BPS -series Ẑ of negative definite plumbed 3-manifolds equipped with a spinc-structure. We express the Δ of Seifert manifolds in terms of an invariant commonly used in singularity theory. We provide several examples illustrating the interesting behaviour of Δ for non-Seifert manifolds. Finally, we compare Δ invariants with correction terms in Heegaard-Floer homology.
