Physical Applicationsortant applications, ranging from studies in the solar system, to galactic structure, to probing cosmological objects. Some of the practical consequences in lensing have been known for a long time and have been predicted early on, whereas other applications popped up only recently. In fact, gravitat

Classification and Genericity of Stable Lens Systemsideally be expressed using maps resistant to small perturbations. This begs investigating the classification and genericity of stable lens systems. The problem then carries over to the time delay families, including the induced time delay functions and lensing maps, used to model gravitational lens

Morse Inequalities inequalities called the .. We shall see in subsequent chapters that the Morse inequalities impact powerfully on several central issues in gravitational lensing: counting lensed images (Chapters 11 and 12), finding lower bounds on total magnification (Chapter 13), and linking the total curvature of
