Mizohata, and L. Hörmander, as well as related results by H. Lewy, Yu. V. Egorov, and other authors including a theorem by J.-M. Bony and P. Schapira [Asterisque 2/3, 108-116 (1973; Zbl 0289.35016)]. The paper is based on a lecture given by the author for secondary school teachers in the framework of the “International Soros Science Educational Program” and is aimed at presenting contemporary developments in mathematics on an elementary level understandable for secondary school teachers and pupils.
