| Abstract | The Riemann problem has been proved to play the role of building blocks in vari-
ous aspects of theory, numerics and applications of one-dimensional conservation laws. In
contrast, the solution structures of two-dimensional Riemann problems are much poorly
understood due to the instantaneous space-time interaction of nonlinear waves which
leads to complex but fascinating wave structures. These structures have the universal
self-similarity feature that reflects the invariant property under dilation. With the self-similarity reduction, the underlying problems change from the purely hyperbolic type to the hyperbolic-elliptic mixed type. In this paper we will formulate and review precisely some mathematical problems with plausible explicit structures in the construction of 2-D Riemann problems and propose some doable problems.
