| Abstract: | An associative commutative algebra of distributions that contains homogeneous and associated homogeneous distributions is constructed. This algebra is used to analyze generalized solutions to strictly hyperbolic partial differential equations. Possible types of singularities are studied and the necessary (analogues of Hugoniót conditions for shock waves) and sufficient conditions for the existence of such solutions are obtained. This paper was written at the request of the Editorial Board. Translated from Teoreticheskaya i Matermaticheskaya Fizika, Vol. 114, No. 1, pp. 3–55, January, 1998. |
