A Construction of Observables for AKSZ Sigma Models

A construction of gauge-invariant observables is suggested for a class of topological field theories, the AKSZ sigma models. The observables are associated to extensions of the target Q -manifold of the sigma model to a Q -bundle over it with additional Hamiltonian structure in fibers.
