Abstract. Quantum groups are one of the most popular objects in the modern mathematical physics. They also play a significant role in other areas of mathematics. It turned out that quantum groups provided invariants of knots and they could be used in quantization of Poisson brackets on manifolds. Quantum groups gave birth to quantum geometry, quantum calculus, quantum special functions and many other “quantum” areas. However, the most important applications of quantum groups relate to the theory of integrable models in the mathematical physics. The presence of the quantum group symmetries (or the so called hidden symmetries) was the crucial point in explicit solutions of many sophisticated non-linear equations such as Korteweg-de Vries or sine-Gordon. Quantum groups changed and enriched representation theory and algebraic topology. The program of these two lectures is based on the development of the problems considered in a joint paper by F. Montaner, A. Stolin, E. Zelmanov (Fields Medal, 1994) “Classification of Lie bialgebras over current algebras” published in Selecta Mathematica New Series (2010), 16:935-962.
