Lie Functor,The main goal of this chapter is to present the procedure for reconstructing a Lie group from its Lie algebra. Moreover, incidentally, we here present certain general mathematical concepts that were already mentioned repeatedly in passing.

Affine Fields and Related Topics,As Exercise 5.5 shows, Lie groups are a particular case of symmetric spaces. This gives us an idea to generalize the construction of the Lie algebra of a Lie group to symmetric spaces. This can be done, but instead of Lie algebras, we obtain more general algebraic objects, as should be expected.

Cartan Theorem,The Lie ternary . constructed in the previous chapter depends on the choice of the point .0∈., i.e., it is a function of the pair (.0). Such pairs are called .. A .: (.0) → (.0) of punctured spaces is a morphism . → . such that .(.0) = .0. It is clear that all punctured symmetric spaces and their morphisms form a category.

Minimal Surfaces,We can replace the real coordinates . and . on a surface . with one complex coordinate . = . + .. In the case where the coordinates . and . are isothermal, the coordinate . is called a . on the surface. (Certain authors also apply this name to the coordinates . and ..)
