| Research Abstract |
Based on ideas inherent in two major advances in the field of geometric analysis, namely, Perelman's resolution of Ricci flow, and Bray's proof of Riemannian Penrose inequality using conformal deformation of Riemannian metrics, the PI has succeeded in generalizing the Penrose inequality, concerning the solution of the Einstein-Maxwell equation. The Investigator Nakamura has also obtained a set of interesting results in the field of nonlinear hyperbolic partial differential equations, which are closely related to the Einstein equation.
Under the support of the current grant, two international meetings were organized in Japan, and together with attending academic meetings abroad, the investigators Yamada and Nakamura established opportunities for exchanges of ideas, which led to the collaboration with Gilbert Weinstein and Marcus Khuri, which in turn became the major work described above.
