Although the first few chapters touch briefly (and critically) on theThom-Zeeman catastrophe theory, most of the book is concerned with more recent and less controversial aspects, covering such topics as: bifurcations and stability loss, wavefront propagation, the distribution of matter

Cutting and Packaging Optimization come about? Ya. B. Zel’dovich in 1970 proposed an explanation of the formation of clusters of dustlike material that is mathematically equivalent to the analysis of the formation of singularities of caustics begun in 1963 by E. M. Lifshitz, Khalatnikov and Sudakov.

Singularities, Bifurcations, and Catastrophes,evolution in mathematics, comparable perhaps to Newton’s invention of the differential and integral calculus. It was claimed that the new science, catastrophe theory, was much more valuable to mankind than mathematical analysis: while Newtonian theory only considers smooth, continuous processes, cat

,Applications of Whitney’s Theory,ingularities of generic mappings, we can try to use this information to study large numbers of diverse phenomena and processes in all areas of science. This simple idea is the whole essence of catastrophe theory.

As well as the previously enumerated singularities, one often meets some further types, which have been given their own names: the ‘.’. the ‘.’ (which Thorn calls the ‘.’) the ‘.’ (which Thorn calls the ‘.’) and so on.
