New exposition of the author’s recent works on singularities of algebraic varieties and principally on three-fold singularities, being also an introduction to the author’s work and of that of Morrison, Stevens, Mori, etc. The author gives a presentation of canonical singularities, terminal singularities, relations and computation of some invariants in terms of the Newton polyhedron.
This paper can also be seen as a review of recent works, but unfortunately it is not very complete, even in the subjects studied.
