It recapitulates author's approach to construction of topological invariants of the Reshetikhin-Turaev-Witten type of 3- and 4-dimensional manifolds in the framework of SU(2) Chern-Simons gauge theory and its hidden (quantum) gauge symmetry.8 pages, tex, no figures (Talk given at the Symposium on Differential Geometry and Mathematical Physics, Banach Center, 1995), some points clarified and a drawing addedQuantum AlgebraHigh Energy Physics - Theorytext
