Topological quantum field theories are interpreted as a generalized form of Morse theory. This interpretation is applied to formulate the simplest topological quantum field theory: topological quantum mechanics. The only non-trivial topological invariant corresponding to this theory is computed and identified with the Euler characteristic. Using field theoretical methods this topological invariant is calculated in different ways and in the process a proof of the Gauss-Bonnet-Chern-Avez formula… 
Topological conformal field theories from gauge-fixed topological gauge theories: a case study
This thesis is devoted to the study of a new construction of two-dimensional topological conformal field theories by gauge fixing two-dimensional topological gauge theories. We study in detail the
Morse Theory in Field Theory
In recent years it has become apparent that topological field theories (TFTs) are likely to be the best candidates for the truly fundamental physical theory. Supersymmetry, for instance, can be
Observables in topological Yang-Mills theory and the Gribov problem
The origin of the nontriviality of observables in topological Yang-Mills theory is discussed from the viewpoint that BRST transformation is the exterior derivative. We show that the appearance of
