Fuchsian reduction is a method for representing solutions of nonlinear PDEs near singularities. The technique has multiple applications including soliton theory, Einstein`s equations and cosmology, stellar models, laser collapse, conformal geometry and combustion. Developed in the 1990s for semilinear wave equations, Fuchsian reduction research has grown in response to those problems in pure and applied mathematics where numerical computations fail. \n\nThis work unfolds systematically in four parts, interweaving theory and applications. The case studies examined in Part III illustrate the impact of reduction techniques and may serve as prototypes for future new applications. In the same spirit, most chapters include a problem section. Background results and solutions to selected problems close the volume. \n\nThis book can be used as a text in graduate courses in pure or applied analysis or as a resource for researchers working with singularities in geometry and mathematical physics. \n\nThis special low-priced edition is for sale in India, Bangladesh, Nepal, Pakistan and Sri Lanka only.
