Abstract
We study the minimal -exponent in the BPS -series of negative definite plumbed 3-manifolds equipped with a spin-structure. We express of Seifert manifolds in terms of an invariant commonly used in singularity theory. We provide several examples illustrating the interesting behaviour of for non-Seifert manifolds. Finally, we compare invariants with correction terms in Heegaard-Floer homology.
