Abstract: (Elsevier)

The basic cohomology for a kählerian topological non linear σ-model is defined by combining the Friedan non-linear splitting symmetry with the BRS symmetry introduced by Witten. It turns out that the basic cohomology can be identified with the De Rham cohomology of the target manifold leading to the observables of the model.
