摘要

A common way in which to build new mathematical objects from old is to take Cartesian products. The product of two additive groups, for example, is a group when equipped with componentwise addition, and the product of two topological spaces is a topological space when equipped with the product topology. In this chapter, we seek to understand the Cartesian product of two affine varieties.
