报告摘要：
Our goal is to explain how the structures arising from the representions of Quantum Groups produce invariant of knots and 3-dimensional manifolds and Topological Quantum Field Theories. We will survey the original construction based on so-called Modular Categories which requires finiteness and semisimplicity. We will then focus on recent non-semisimple developments. In each case we will illustrate the general categorical setting by examples obtained from variants of the sl(2) Quantum Group.
