Abstract

Given a closed symplectic 4-manifold (X,ω)(X,\omega), we define a twisted version of the Gromov-Taubes invariants for (X,ω)(X,\omega), where the twisting coefficients are induced by the choice of a surface bundle over XX. Given a fibered 3-manifold YY, we similarly construct twisted Lefschetz zeta functions associated with surface bundles: we prove that these are essentially equivalent to the Jiang's Lefschetz zeta functions of YY, twisted by the representations of π1(Y)\pi_1(Y) that are induced by monodromy homomorphisms of surface bundles over YY. This leads to an interpretation of the corresponding twisted Reidemeister torsions of YY in terms of products of "local" commutative Reidemeister torsions. Finally we relate the two invariants by proving that, for any fixed closed surface bundle B\mathcal{B} over YY, the corresponding twisted Lefschetz zeta function coincides with the Gromov-Taubes invariant of S1×YS^1 \times Y twisted by the bundle over S1×YS^1 \times Y naturally induced by B\mathcal{B}.
