The 2000 David Blackwell Lecturer was Arlie O. Petters. Dr. Petters also coorganized CAARMS 7. Now there is a book, Singularity Theory and Gravitational Lensing by A. O. Petters, H. Levine, and J. Wambsganss. In gravitational lensing, the image from a distant cosmic object appears to split into multiple images due to the effect of gravitational force exerted by massive intervening objects between them and Earth. Here it is mathematically demonstrated how gravity from not just one or two objects… 

Gravity ’ s Action on Light

G ravitational lensing is the action of gravity on light. The subject has become a vibrant area in astronomy and mathematical physics with great predictive power. The field cuts across geometry,

Gravitational Lensing by Rotating Naked Singularities

We model massive compact objects in galactic nuclei as stationary, axially symmetric naked singularities in the Einstein-massless scalar field theory and study the resulting gravitational lensing. In

Gravitational Lensing by Elliptical Galaxies, and the Schwarz Function

We discuss gravitational lensing by elliptical galaxies with some particular mass distributions. Using simple techniques from the theory of quadrature domains and the Schwarz function (cf. [18]) we

Gravitational Lensing from a Spacetime Perspective

TLDR
The theory of gravitational lensing is reviewed from a spacetime perspective, without quasi-Newtonian approximations, and includes general theorems on the classification of caustics, on criteria for multiple imaging, and on the possible number of images.

Fermat potentials for nonperturbative gravitational lensing

The images of many distant galaxies are displaced, distorted and often multiplied by the presence of foreground massive galaxies near the line of sight; the foreground galaxies act as gravitational

Theoretical gravitational lensing. Beyond the weak-field small-angle approximation

An overview is given on those theoretical gravitational lensing results that can be formulated in a spacetime setting, without assuming that the gravitational fields are weak and that the bending

Gravitational lensing by a black-bounce-Reissner–Nordström spacetime

We investigate the weak and strong deflection gravitational lensing by a black-bounce-Reissner–Nordström spacetime and obtain their lensing observables. Assuming the supermassive black holes in the

Mathematics of gravitational lensing: multiple imaging and magnification

The mathematical theory of gravitational lensing has revealed many generic and global properties. Beginning with multiple imaging, we review Morse-theoretic image counting formulas and lower bound

Gravitational lensing in fourth order gravity

Gravitational lensing is investigated in the weak field limit of fourth order gravity in which the Lagrangian of the gravitational field is modified by replacing the Ricci scalar curvature $R$ with
