Since the 1980's there have been several breakthroughs in nonlinear dynamics and turbulence. Of particular importance to this proposal are: a) the development of scale invariance as a general and powerful nonclassical symmetry; b) the discovery of multifractals and their relation to turbulent cascade processes. During the next five years I propose to build on this in several ways:

自20世纪80年代以来，在非线性动力学和湍流方面取得了一些突破。 对这一提议特别重要的是：a）发展了尺度不变性作为一种普遍而有力的非经典对称性; B）发现了多重分形及其与湍流级联过程的关系。 在今后五年中，我建议以几种方式在此基础上再接再厉：
