**Morse Theory in Field Theory**

**Abstract:**

In resent years it becomes apparent that topological field theories
(TFTs) are likely the best candidates for truly fundamental physical theory.
Supersymmetry, for instance, can be motivated and expressed in terms of
TFTs. Here I build simple example of TFT using Morse theory and Massey
product. Action (invariant under

supersymmertic transformations) is constructed and relations for correlators
in this theory are obtained. During making this theory theorem about connection
between Euler characteristic of a manifold and sum of indexes of critical
points is proved for arbitrary dimension of the target space.
