Reviews

This book presents some results of the study of singularities within the field of algebraic geometry. ... The text is clear and well written and it is accessible to non-expert readers. ... the author defines all the concepts and the results are either proved or a reference is provided. This makes the book self-contained in a broad sense. It is a useful volume both for readers studying singular varieties for the first time and for experts on classification of singularities. (Santiago Encinas, Mathematical Reviews, August, 2015)
