Due to the lack of proper bibliographical sources stratification theory
seems to be a "mysterious" subject in contemporary mathematics. This
book contains a complete and elementary survey - including an extended
bibliography - on stratification theory, including its historical
development. Some further important topics in the book are: Morse
theory, singularities, transversality theory, complex analytic
varieties, Lefschetz theorems, connectivity theorems, intersection
homology, complements of affine subspaces and combinatorics. The book is
designed for all interested students or professionals in this area.
