摘要: Assume temporarily that h is a flat metric on F . Let K be smooth triangulation of Z We can define the Reidemeistermetric ‖ λ(F ) ). It basic result Franz [13], Reidemeister [29], and de-Rham [30] (see also [25, §8]), does not depend The then topological invariant If H (Z,F = 0, it positive number, now called torsion (or Rtorsion).
