摘要

In the introduction to Chapter 4, the reader was encouraged to ask a key question whenever a new type of mathematical object is introduced: which maps between these objects preserve their relevant structure? For affine varieties, we landed upon polynomial maps as the appropriate notion of structure-preserving maps, and the first goal of this chapter is to define a corresponding notion in the projective setting.
