It is known that perturbative invariants of rational homology 3–spheres can be
constructed by using arithmetic perturbative expansion of quantum invariants of
them. However, we could not make arithmetic perturbative expansion of
quantum invariants for 3–manifolds with positive Betti numbers by the same
method.
In this paper, we explain how to make arithmetic perturbative expansion of
quantum SO(3) invariants of 3–manifolds with the first Betti number 1. Further,
motivated by this expansion, we construct perturbative invariants of such
3–manifolds. We show some properties of the perturbative invariants, which imply
that their coefficients are independent invariants.
