Numerical methods,ot known a priori. There are other problems where numerical analysis must be applied, e.g., if one wants to determine the total magnification for an extended source, as a function of its position. This problem is computationally simpler than the standard problem.

Friction-Induced Nucleation of Nanocrystals,ins a summary of those aspects of cosmology which are relevant for lens theory, together with some background material. On this basis, the second topic is treated in Sects. 4.5 and 4.6. Finally, in Sect. 4.7 we consider some aspects of wave optics, in preparation for Chap. 7.

https://doi.org/10.1007/978-981-15-1664-1e in light-travel-time for different images of a source is an observable; this time delay is one of the central quantities in gravitational lensing. Two general theorems are proved in Sect. 5.4, and a classification of 3-image and 5-image topographies is presented in Sect. 5.5.
