Abstract : The specific nature of the blast wave problem as a boundary (initial) value problem with moving boundaries in the theory of a system of quasilinear partial differential equations gave the impetus for developing an approach which is based on geometricanalytical grounds. The idea is to make maximum use of the geometric configuration of the shock wave itself by employing a socalled 'natural system of coordinates'. This makes it possible to handle the shock transition conditions in a relatively simple manner. Furthermore, the boundary value problem with moving boundaries is reduced to a problem with fixed boundaries in a spacetime continuum. As a consequence, the blast wave problem can be treated as an initial value problem in the classical sense. (Author)
