最简单的近藤问题是完全在铁磁的情况下处理，并给出了确切的界限，在反铁磁的情况下，通过使用一个缩放技术的渐近精确表达的基态属性。该理论还解决了n= 2的一维伊辛问题的情况。铁磁情形有有限自旋，而反铁磁情形没有真正奇异的T→ 0性质（例如，它有有限的χ）。
The simplest Kondo problem is treated exactly in the ferromagnetic case, and given exact bounds for the relevant physical properties in the antiferromagnetic case, by use of a scaling technique on an asymptotically exact expression for the ground-state properties given earlier. The theory also solves the n= 2 case of the one-dimensional Ising problem. The ferromagnetic case has a finite spin, while the antiferromagnetic case has no truly singular T→ 0 properties (eg, it has finite χ).
