Query: The algebraic construction of the Novikov complex of a circle-valued
  Morse function   The Novikov complex of a circle-valued Morse function is constructed
algebraically from the Morse-Smale complex of the restriction to a fundamental
domain of the real-valued Morse function on the pullback infinite cyclic cover.
