WebIn Section 3 we look at various types of morphism between bicategories or 2-categories: strict, pseudo, lax, partial; and see how these can be used to describe enriched and indexed categories. In Section 4 we begin the study of 2-dimensional universal algebra, with the basic definitions and the construction of weak morphism classifiers. Webmorphism, then for every y2Y, the ber f 1(y) is a complete variety (possibly empty). Exercise 1.6. Show that if X is a connected, complete variety, then ( X;O X) = k. Deduce that a complete variety is also a ne if and only if it is a nite set of points. Exercise 1.7. Show that if f: X !Y and g: Y !Z are morphisms of algebraic

Hartshorne exercise 1.3.17) We say X is an affine variety if it is an irreducible closed subset of An. (see the definition after example 1.1.4 of Hartshorne) Now let X and Y be affine varieties and φ: X → Y a dominant morphism.

WebA morphism of 2-crossed modules of algebras can be defined in a obvious way. We thus define the category of 2-crossed module denoting it by X2Mod.
