During the last 30 years, Mode-Coupling Theory (MCT) has emerged as the only microscopic theory of the dynamics of dense liquids with experimental relevance. Its success lies largely on its ability to predict a number of observables over a broad range of systems. Applying MCT to two- and three-dimensional liquids, both in and out of equilibrium, notably provides the full wave-vector dependence of dynamical correlators with quantitative accuracy. As any approximate theory, however, MCT has a drawback: the validity of the approximations on which it is based has to be checked on a case-to-case basis. As an example, a correct description of the dynamics close to jamming has so far not been achieved within MCT. At the same time, a complementary description has been obtained from the exact solution to the dynamics of liquids in infinite dimensions. Being an exact solution, this framework is, by definition, guaranteed to be applicable in all possible regimes, and it is also physically consistent with thermodynamic approaches in the long time limit. However, this formalism is completely inaccurate in two and three dimensions, and neglects the wave-vector dependence of correlators, hence it can only provide qualitative insights into the behavior of physically relevant systems. This focused and informal workshop aims to find a theoretically sound way of unifying the two descriptions into a single framework that would have the advantages of both.
