摘要：
在这个讲座中，一些必要的数学工具，适当的描述海森堡反铁磁体。我们想指出有限自旋系统的海森堡哈密顿量在铁磁和反铁磁情况下的区别。基态性质进行了讨论。
英文摘要：
In this lecture some mathematical tools necessary for a proper description of the Heisenberg antiferromagnet are presented. We would like to point out differences between ferro- and antiferromagnetic cases of Heisenberg Hamiltonian for finite spin systems. The ground-state properties are discussed.
