摘要

Generally, the solution of this problem has a flowery singularity structure issuing from the origin; hence the solution can not be regarded as a perturbation of a solution to one-dimensional problem. Therefore, the initial problem is called essentially multi-dimensional problem. When the initial data are composed of different constants, and all F_i are straight lines, the problem is called multi-dimensional Riemann problem, which was first put forward in ref. [1]. Meanwhile, the authors of refs. [2—5] studied self-similar solutions of this problem in some simplest cases.
