Characterization of a convex obstacle by singularities of the scattering kernel. (English) Zbl 0611.35066
The author studies relations between singularities of the scattering kernel of the wave equation in an exterior domain and the convexity of the obstacle. He gives a necessary and sufficient condition to have convexity.
