Sixth, it's pointed out that the equilibrium is unstable in some structural growth models with more specific forms, and business cycles may possibly arise in those models. And it shows that in some cases the invisible hand not only won't lead to an equilibrium, furthermore, will lead to business cycles.

第六，指出在一些形式更为具体的结构增长模型中均衡是不稳定的，且可能出现经济周期，从而说明在一些情况下"看不见的手"不仅不会导致均衡，反而会带来经济周期。

At present time thesemaps have become important objectors and tools in studying operator algebras. Nestalgebras is a class of most importaut non-semisimple, non-prime and non-self adjointoperator algebras.
