Principal Investigator: C. Robin Graham
The investigator will carry out several research projects studying various aspects of conformal geometry and asymptotically hyperbolic metrics. These include analyzing a Dirichlet-to-Neumann map for Poincare-Einstein metrics, studying the boundary rigidity problem for asymptotically hyperbolic metrics, and developing the theory of the ambient metric in even dimensions beyond the obstruction. The main objectives are to further understanding of these geometries and their relationship. The methods are analytic, geometric, and algebraic, with an intimate connection between these different aspects of the study.
This project will study the relationship between different geometric structures: conformal geometry on the one hand and asymptotically hyperbolic geometry on the other. Conformal geometry is the study of properties of space which depend only on angles but not on distances. Hyperbolic geometry involves spaces of negative curvature, in which the analogues of straight lines separate more than in usual flat space. Several projects will study the relationship between these geometries. Apart from the intrinsic geometric interest, one motivation is the AdS/CFT correspondence in Physics, a proposed holographic correspondence for certain physical phenomena. The proposed activity will further enable the development of human resources through educationally oriented activities of the investigator, including advising, mentoring and teaching graduate students, and curricular development. International cooperation and partnership will be promoted. Ties between the mathematics and physics communities will be enhanced. The results will be effectively disseminated through attendance and speaking at meetings and conferences and through posting and publication of articles.
