Abstract Let M be a closed n-dimensional manifold, n > 2 , whose first real cohomology group H 1 ( M ; R ) is non-zero. We present a general method for constructing a Morse 1-form α on M, closed but non-exact, and a pseudo-gradient X such that the differential ∂ X of the Novikov complex of the pair ( α , X ) has at least one incidence coefficient which is an infinite series. This is an application of our previous study of the homoclinic bifurcation of pseudo-gradients of multivalued Morse functions.
