我们对 IRn 的紧凸仿射图集的极值点进行分类，将其映射到闭单位球本身。这项工作是解决寻找 N×N 密度矩阵（N 级系统的动态映射）的仿射映射的紧凸集的极值点问题的初步步骤，并且 forn=3 在两级系统的最简单情况下提供了该问题的解决方案。
We classify the extreme points of the compact convex set of affine maps of IRn which map into itself the closed unit ball. This work is a preliminary step towards solving the problem of finding the extreme points of the compact convex set of affine maps of theN×N density matrices (dynamical maps of anN-level system) and forn=3 furnishes the solution of the problem in the simplest case of a two-level system.
