Resume :

The study of special type surfaces in homogeneous 3-spaces has known a great development in last years. As well known, Thurston established eight simply connected homogeneous 3D geometries and formulated the famous conjecture saying that every compact 3-manifold admits a canonical decomposition into pieces, each of them carrying one of these geometries. Thurston himself proved a part of this fact which was completed by Perelman. His result motivates a deep study of these simply connected homogeneous Riemannian spaces for a better understanding of them. A good comprehension of such a space is supported by the study of the properties of its submanifolds (curves, surfaces, hypersurfaces). The project we propose is a natural continuation of the research developed by the PI in last 4 years, either by himself or in collaboration with researchers both from Europe and USA. The aim of this project is to investigate some special types of surfaces (e.g. constant angle surfaces, translation surfaces or Weingarten surfaces) as well as to explore magnetic trajectories in certain homogeneous 3-spaces. Geometric characterizations and classification theorems will be given, and part of the obtained results will be extended to higher dimensions. Moreover, other spaces endowed with indefinite metrics will be considered. Last but not least, our purpose is to build a unified research team whose scientific results will have an international relevance in the scientific community.


Objectives :

The exploration of the geometric properties of surfaces embedded in homogeneous spaces of dimension 3 represents a contemporary subject of wide interest. Actually, the study of surfaces in 3-dimensional Thurston geometries has grown considerably in the last decade. Maybe the most important reason is the announced proof of the Thurston geometric conjecture which ensures the dominant role of these spaces among 3D geometries. Fundamental quantities in homogeneous spaces Nil3 and Sol3, such as curvatures, geodesics or holonomy groups, came also recently in attention of mathematicians, but their geometry is far to be completely known. Some other problems arising from physical phenomena may be modeled in these spaces and this aspect makes the study of curves and surfaces in homogeneous spaces (in particular space forms) more attractive.
