US-France Cooperative Research: Discrete Groups, Representation Varieties, and CR-Geometry

0232724温特沃斯这个为期三年的美国-法国数学合作涉及理查德A。约翰霍普金斯大学的温特沃斯和巴黎第六大学的伊莱沙·法尔贝尔。这个项目的目标是在离散群和低维流形的几何分析领域集中合作研究。 他们将研究U（n）中曲面群的表示以及球面CR流形的变形理论和刚性问题。 美国调查员带来了这种合作的专业知识，在几何分析方面的代表性的表面群体。 这是补充法国的专业知识在CR流形，离散群及其变形。该奖项代表了美国方面向NSF和法国国家科学研究中心（CNRS）提出的联合建议。 NSF将为美国研究员和研究生支付旅费和生活费。 CNRS将支持法国研究人员和学生访问美国。 美国和法国的研究生将受益于国际研究方法和国际曝光他们的工作。

0232724WentworthThis three-year award for U.S.-France collaboration in mathematics involves Richard A. Wentworth at Johns Hopkins University and Elisha Falbel at the University of Paris VI. The objective of this project is a concentrated collaborative research effort in the area of discrete groups and geometrical analysis of low dimensional manifolds. They will study representation of surface groups in U (n) and the deformation theory and rigidity issues of spherical CR manifolds. The U.S. investigator brings to this collaboration expertise in the geometrical analytic aspects of representations of surface groups. This is complemented by French expertise in CR manifolds, discrete groups and their deformations. This award represents the U.S. side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the U.S. investigator and graduate student. The CNRS will support the visits of the French researcher and student to the United States. U.S. and French graduate students will benefit from the international approach to research and international exposure for their work.
