Duality from topological symmetry

We describe topological gauge theories for which duality properties are enc oded by construction. We study them for compact manifolds of dimensions fou r, eight and two. The fields and their duals are treated symmetrically, wit hin the context of field-antifield unification. Dual formulations correspon d to different gauge-fixings of the topological symmetry. We also describe novel features in eight-dimensional theories, and speculate about their pos sible "Abelian" descriptions.
