Self-Similar or Group Solutions

In this chapter we have collected fairly miscellaneous problems with reference to a unified methodological criterion, namely, their self-similarity (cf. Section 1.12), which leads to reduction in their dimensionality, thus simplifying their solution. At the same time, the problems thus made canonical, together with their solutions, allow one to make more definite conclusions on local and global properties of the flows of more general classes.
