# Reidemeister Torsion in Floer--Novikov Theory and Counting pseudo-holomorphic tori, II

@article{Lee2001ReidemeisterTI, title={Reidemeister Torsion in Floer--Novikov Theory and Counting pseudo-holomorphic tori, II}, author={Yi-Jen Lee}, journal={Journal of Symplectic Geometry}, year={2001}, volume={3}, pages={385-480} }

This is the first part of an article in two parts, which builds the foundation of a Floer-theoretic invariant, (I_F). (See math.DG/0505013 for part II).
The Floer homology can be trivial in many variants of the Floer theory; it is therefore interesting to consider more refined invariants of the Floer complex. We consider one such instance--the Reidemeister torsion (\tau_F) of the Floer-Novikov complex of (possibly non-hamiltonian) symplectomorphisms. (\tau_F) turns out NOT to be invariant…
