Gårding, Lars Hyperbolic equations in the twentieth century. (English) Zbl 1044.01525 Material on the history of mathematics in the 20th century. Proceedings of the colloquium to the memory of Jean Dieudonné, Nice, France, January 1996. Marseille: Société Mathématique de France (ISBN 2-85629-065-5/pbk). Sémin. Congr. 3, 37-68 (1998). This survey shows the development of the theory of hyperbolic equations in the 20th century with the focus on the problem of the propagation of singularities. Results on boundary value problems are also given.For the entire collection see [Zbl 0892.00028].
