As a corollary, we solve a conjecture of Liao, i.e., the following four conditions are all equivalent: 1 the system is structurally stable, 2 the system is in the interior of the set of Kupka-Smale systems, 3 the obstruction set and the interior of singularities of the system are empty, 4 the system satisfies Axiom A and the strong transversality condition.

作为一个推论，这解决了廖山涛先生的一个猜测，即下述四个条件等价：1 系统为结构稳定的，2系统及其附近的系统皆为Kupka-Smale系统，3系统的阻碍集为空集，4 系统为公理A且满足横截性条件。3→4，4→1，1→4已经分别由廖山涛， Smale、 Anosov、 Robbin、 Robinson以及Robinson完成。

It is interesting that a focus on practice as opposed to cognition was already adumbrated in Richard Courant's and Herbert Robbins' classical text titled What is Mathematics?

有意思的是以反对认识而强调实践的观点在Richard Courant（哥挺根学派的理查德·克朗和Herbert Robbin的1941年的经典论文&什么是数学&中表达了出来）。
