Aim of this talk is to propose a notion of parallel transport for spaces, which are metric measure spaces satisfying lower Ricci curvature bounds in a generalised sense. The first part of the seminar will be devoted to the description of the calculus tools that are already available in such nonsmooth framework and to the development of some new functional spaces that will constitute the setting for our theory. In the second part we will give the definition of parallel transport and prove both its wellposedness and uniqueness. Some geometric consequences of the existence of this concept of parallel transport will be shown to hold, in primis the constant dimension of the underlying spaces. As a last step, we will provide existence of the parallel transport for a special class of finitedimensional spaces. The existence for general spaces is still an open problem. This is a joint work with Nicola Gigli.
