**Objectives**:

The project is devoted to all aspects of homogeneity and genericity in metric groups, functional analysis and dynamical systems. Various Fraïssé constructions will be investigated, e.g. for the Jacelon-Razak and Jiang-Su C*-algebras, as well as a non-compact counterpart of the Poulsen simplex. We will also construct and analyze Polish spaces of bounded linear operators, actions of finitely generated groups on compact metric spaces and representations of countable groups. Absolute homogeneity for metric spaces and dilation groups will be examined and we will also generalize Pontryagin duality to the framework of metric groups. Moreover, we will extend the theory of Katětov functors to metric Fraïssé classes and study its relations to universality of automorphism groups of Fraïssé limits and Borel reducibility of isomorphism relations. The theory of Borel reduciblity will be also investigated in the more general framework of pseudometrics.
