This note describes the functional-integral quantization of two-dimensional topolog- ical field theories together with applications to problems in deformation quantization of Poisson manifolds and reduction of certain submanifolds. A brief introduction to smooth graded mani- folds and to the Batalin–Vilkovisky formalism is included. Mathematics Subject Classification (2000). Primary 81T45; Secondary 51P05, 53D55, 58A50, 81T70.

The basic setting. Let be a smooth compact 2-manifold. On M1 := ()⊕ 1() one may define the following very simple action functional: S(ξ,η) := η dξ, ξ ∈ 0(), η ∈ 1(), (1.1) which is invariant under the distribution 0 ⊕ dβ, β ∈ 0().
