Euler Figures, Unidirectional Multivalued Waves, Quanta, and Vortices
摘要
In this chapter, we will consider mainly unidirectional waves. We are interested in questions of how, in the process of one or another evolution, they can be transformed into multivalued waves. In particular, how the unidirectional waves transform into the Euler figures, particle-waves, or a train of particles.
