Lectures on K3 Surfaces (Cambridge Studies in Advanced Mathematics, Series Number 158) Illustrated Edition

The author explicates several definitions about the K3-surfaces, which are shortly the same thing of the Enriques surfaces. Those objects are related by a particular function. The K3-surfaces have an important correlation with the Picard group. So we have several structures mixing traditional geometry and algebra, what that produces a new matter, named algebraic geometry. It is a new interesting way of telling old arguments.
