Gravitational Lensing and Optical Geometry A Centennial Perspective
Book · December 8, 2020 The articles assembled in this volume contain original research and reviews and apply a variety of mathematical techniques that have been developed to study this effect, both in 3-space and in spacetime. ... CiteThe isoperimetric problem in riemannian optical geometry
Journal Article Pure and Applied Mathematics Quarterly · January 1, 2020 In general relativity, spatial light rays of static spherically symmetric spacetimes are geodesics of surfaces in Riemannian optical geometry. In this paper, we apply results on the isoperimetric problem to show that length-minimizing curves subject to an ... Full text CiteEducation, Training & Certifications
