An Introduction to topological field theories

The string model with /ital N/=2 world-sheet supersymmetry is approachedvia ghosts, Becchi-Rouet-Stora-Tyutin cohomology, and bosonization. Someamplitudes involving massless scalars and vectors are computed at the treelevel. The constraints of locality on the spectrum are analyzed. An attempt ismade to ''decompactify'' the model into a four-dimensional theory.
