We show that for any closed symplectic manifold, the number of 1-periodic orbits of a non-degenerate Hamiltonian is bounded from below by a version of total Betti numbers over Z, which takes account of torsions of all characteristic. The proof relies on the construction of a Hamiltonian Floer theory over Z, which further depends on our early work with Xu and a construction of Kuranishi flow category with smooth global charts generalizing recent work of Abouzaid-McLean-Smith. This is joint work with Guangbo Xu.
