报告摘要: Thurston geometries are an interesting class of Riemannian homogeneous spaces, which play a fundamental role in geometrization theorems. In this talk we discuss a classification result of Codazzi hypersurfaces (including parallel and totally geodesic hypersurfaces) in the 4-dimensional Thurston geometries Sol^4_1 and Sol^4_0. Moreover, we analyse the structure of Sol^4_(m,n), Nil^4 and F^4. Before doing so, we motivate the study of Thurston geometries in general by looking at the geometrization in dimension 2 and 3: the uniformization of surfaces and the Thurston geometrization conjecture, respectively. From this it becomes clear that Thurston geometries can be thought of as model spaces. In addition, we mention some results of other authors on submanifolds in Thurston geometries, showing that there has already been great interest in this field from a Riemannian point of view.
