On Bi-Lipschitz Classification of Real and Complex Singularities
摘要
Lipschitz geometry of singularities is the local study of algebraic/analytic (semi-algebraic/subanalytic) sets up to bi-Lipschitz homeomorphisms. Results by Mostowski [35] and Parusiński [40] guarantee that there is only infinite many countable of such singularities up to bi-Lipschitz homeomorphism, in other words, they can be classified by means of discrete invariants. This text aims to introduce the known results of the bi-Lipschitz classification of singularities; these notes complement and intersect the articles that also provide an introduction to the subject [20, 28, 39, 43, 44].
